YMMV / GAMERA -Rebirth-

• Alternative Character Interpretation:
  • Jun joins the boys in staring at the sunbathing Emiko. Was this a display of Even the Girls Want Her for Jun, implying she might be interested in Emiko or women in general? Or was Jun admiring Emiko’s self confidence as a woman which Jun seems to lack? Junichi does look up to Emiko both as an older sister type and a female role model in an otherwise male dominated environment. Jun does appear to downplay her own feminine traits while leaning more toward her tomboyish nerdy side so it’s likely she admires Emiko for seemingly embracing both.
  • The Hemueden and by extension The Eustace Foundation. Just who are they really or more importantly what are they? Despite living on Earth 100,000 years ago, they appear almost inhuman, seemingly lacking any real emotions or even empathy for those around them, with only Emiko showing any signs of emotion. Even when things aren’t quite going their way like Emiko’s betrayal or the realization that they're short on food supplies, they appear more amused by the situations instead of angry. Considering that they own spacefaring equipment and have a moon base - as well as more advanced technology than the military - and the main board members appear to have some form of immortality, it’s quite possible they were never even from Earth to begin with.
• Awesome Music:
  • Natsuake by Wanima, the animes' opening.
  • Fly & Dive by Wanima, the animes' credits for the first five episodes.
  • Anger, or "Gamera's Theme" to some. When it plays, be sure Gamera is going to show his enemies exactly why he's called The Invincible Super Monster.
  • An acoustic rendition of Gamera March in the final episodes credits.
• Catharsis Factor:
  • For a non-fatal example, seeing the bullies that were with Brody in the first episode running in terror from Gyaos after beating up Boco's group was incredibly fun to watch.
  • Generally speaking, any time Gamera shows the Monster of the Week what for. The animalistic, almost sadistic aggression of the monsters he faces and the horrible things they aim to do makes the No-Holds-Barred Beatdown he inflicts on them all he more satisfying.
  • For her betrayal of the kids by attempting to feed them to Viras, it is great to see Emiko be devoured entirely by a baby Gyaos that indifferently burps out her ring afterwards.
  • After everything the Eustace Foundation board has done, it's quite satisfying to see Gamera obliterate them. Even better, they believed their plans were about to succeed just as the beam wipes them all out.
• Complete Monster: Nora Melchiorri is a member of the board of the Eustace Foundation, and the primary leader of their conspiracy. The daughter of a prominent family descending from the Hemueden civilization, Nora previously secured her position by having her sister killed. Seeking to reinstate Hemueden's plans for the world, Nora and the Board engineer the awakening of several kaiju, with thousands of innocent people being slaughtered and devoured; the endgame being the extermination of the human race, save for those they deem "worthy" to inherit. To control the kaiju, the board seeks out a child with a specific genetic "code" to sacrifice. When Nora's treacherous niece, Emiko, attempts and fails to usurp her, Nora reveals a new trump card: having previously experimented on an infant Gyaos, Nora further mutates it before setting it loose to finish things off. Failing that, Nora attempts to brainwash Gamera with a virus to carry out their plans. No tears are shed when she and her associates meet their end at the hands of Gamera.
• Funny Moments: In an extremely weird way, the deaths of the Eustace Foundation board is funny, if only for how they straight up don't see it coming at all. So just watching them be evaporated by Gamera without even noticing his attack is hysterical.
• Harsher in Hindsight: The fact that Tazaki is divorced becomes this when his voice actor Mamoru Miyano announced his divorce on his website just 3 months after the release of this series. Especially harsher considering that unlike his character, who doesn't like children and doesn't want to have them, Miyano ironically had a son before the divorce happened.
• Heartwarming Moments: The acoustic rendition of the classic Gamera March as the end credits song. Doubly so if you know the Japanese lyrics, which set to the new melody make it sound like a soothing, hopeful piece assuring the kids that Gamera will always be their to protect them.
• Improved Second Attempt: This is both Polygon and Hiroyuki Seshita's second attempt at making a kaiju anime, the first being Godzilla Anime Trilogy. GAMERA -Rebirth- has received a far warmer reception and most fans consider it much better. Ironically, Seshita has explained in an interview that he recycled what he original intent for the Godzilla Anime Trilogy was before Executive Meddling kicked in.
• Jerkass Woobie: Douglas is shown to lord it over the Japanese due to being the son of a U.S. general, taking their money and beating up smaller kids. That said, being stuck between the humiliation conga of nearly being killed by Gyaos and Jiger along with trying to live up to his dad's standards doesn't excuse his behavior but explains why he is that way. It helps that he gets some much needed character development that makes him a likeable character.
• Memetic Mutation:
  • Comparing Gamera's theme to a truck commercial as seen under narm charm.
    • It’s also been compared to the intro of this YouTube cooking channel.
    • “Just let the knife do the work” fillets Zigra using Guiron’s severed head
  • The Rebirth Jiger not being Jiger at all but Nezura, the giant rat horror movie that was cancelled then prop recycled to make the first Gamera, in disguise.
  • Gamera's death in the final episode, where he fades into dust and dissipates into the wind, has been jokingly compared to Master Oogway's ascension from Kung Fu Panda.
  • Yassified Metphies, AKA Emiko. Both are blonde and pale-skinned, and both are manipulative and mentor figures to the protagonists. Metphies refers to Ghidorah as “the Golden Demise”, and Emiko refers to Viras as “the Golden Devil”. The fact that both of them are from Polygon Studios projects that were handled by the same director highlights the hilarity.
  • Gamera's final attack blasting the moon was very quickly compared to the infamous Sonic Adventure 2 Real-Time Fandub involving Alfred Coleman's legendary lunar tirade when Dr. Eggman... let's say "assaulted" the moon in a similar manner.
• Moe: Gamera's baby form. Just look at him!◊
• Moral Event Horizon:
  • The Eustace Foundation crossed it 100,000 years ago when they fed children to the Kaiju in order to control them and kill the vast majority of humanity, which they also plan to do in the modern day.
  • That goes double for Emiko, who not only was on board with the Foundation's plan from the beginning before deciding to turn on them for her gains, but also pretended to be a friend to the kids, especially to Junichi, to get them to trust her.
  • Nora crossed the line when it is revealed that she killed her sister to usurp her.
• Narm Charm: Gamera's battle theme wouldn't sound out of place from a truck or power tool commercial. None the less it works to get the blood pumping as Gamera takes on his enemies.
• Special Effects Failure: In one scene where the kids are captured, they're holding their hands out in a matter which shows that they're supposed to be tied up, but there are no visible restraints whatsoever.
• Tainted by the Preview:
  • When the first trailer was released, many people complained about the effects for the monsters looking bad, or that the humans looked stiff.
  • Others were leery of another kaiju anime from Polygon Studios, after the extremely divisive Godzilla Anime Trilogy and Pacific Rim: The Black, both of which are considered So Okay, It's Average at best. The fact that Rebirth is sharing a director with the anime trilogy did nothing to smooth matters over. Nor did the involvement of studio ENGI as co-producer, who at that point only had middling 2D productions like the adaptations of Management of Novice Alchemist and The Detective is Already Dead to their name, and only a few supporting efforts such as So I'm a Spider, So What? on CGI duties.
  • Still more people pointed out that unlikable human characters were frequently considered the weakest part of Polygon's previous kaiju outings- and that that could spell disaster here, since a good Gamera story relies more heavily on its human cast and their relationships to the kaiju than most other kaiju stories. Thankfully upon release most audiences agreed the human cast this time around was rather solid.
• Tear Jerker:
  • The reveal in Joe's past that his mother and younger brother died in an accident, which is why his father has become neglectful and alcoholic.
  • Emiko's betrayal deeply hurts the kids, especially Junichi, after all the times she and the group bonded over the first few episodes.
    • Emiko herself looks especially hurt by Junichi no longer considering her as a friend when she tried to spare the latter on that account then afterwards Emiko coldly has Junichi get fed to Viras along with the boys. Considering that Emiko mentioned she had no friends while growing up, it's no wonder.
  • Joe's sacrifice at the penultimate episode. Boco tearfully begged Joe not to leave him and Boco's eyes become blank as they were falling.
• Viewer Gender Confusion: Many viewers thought that Junichi was a boy, due to her complete lack of any feminine attributes (having very short, wavy hair and unisex clothing) or interests (she's depicted as a bookish nerd type interesting in military hardware and the paranormal), and the Gamera franchise previously focusing only on boys as a the main characters (with girls usually being sidelined, apart from Asagi, Nagamine, and Ayana in the Heisei Trilogy). This is aided by the fact that Boco and Joe, who've known her since 3rd grade, treat her as just one of their gang and assume it's no big deal to anyone that she isn't a boy. Even in the story, it takes Brody several episodes before he finds out that Junichi is a girl (and Boco and Joe react with "you couldn't tell?"), which leads to a few blink-and-you-miss-it Ship Tease moments.
• Visual Effects of Awesome: While the CGI on the humans isn't the best, the animation for the Kaiju fights is amazing, being able to be fluid and fast-paced while also conveying the sheer size of the monsters and the impact of their blows.
