History YMMV / MightyMorphinPowerRangers

* RootingForTheEmpire: Sure, they may have been cheesy and ridiculous-looking (when they weren't hideous), but you just can't help but root for Bulk & Skull (at the very least antagonists during the first two seasons). The main villains got this as well, as they were at the very least more interesting than the flat [[TastesLikeDiabetes goody-good]] Rangers.

** A good number of lines delivered when the Rangers are morphed. Turned UpToEleven mid-season two when Jason, Trini and Zack are voiced by sound-alikes due to their actors quitting; while Zack's replacement voice actually does a passable impression of Creator/WalterEmanuelJones, Trini's doesn't sound much like Thuy Trang, while Jason is voiced by someone who not only sounds absolutely nothing like Austin St. John, but simply cannot act to save his life.

** "Switching Places" is pretty disappointing as a FreakyFridayFlip story, not least because Billy and Kimberly switching bodies has no impact at all on the fight scenes later. At the very least, they could have messed with the TransformationSequence to have one or both of them say the wrong animal at first, [[HilariousInHindsight Like Gokaiger did years later.]]

* LGBTFanbase: Jason. He hangs around a gym, tends toward fanservice as much as any other male ranger, is always hanging around Tommy...The false gay porn rumors only made it worse. Also, Zedd for that metal codpiece.
** This itself is HarsherInHindsight considering all the crap David Yost took from members of the crew about his sexuality.

** Rocky was put in a weird position due to his status as the Red Ranger [[ThePiratesWhoDontDoAnything but never actually leading the team]], due to Tommy becoming leader before he was introduced. He was also not seen as very interesting due to his more generic personality that wouldn't be established until ''Zeo'' made him somewhat a comedic character. The fact that he also replaced Jason, one of the most popular Rangers of the franchise, Red or otherwise, did not help.

* SpecialEffectFailure: For some reason still unknown to this day, Saban apparently couldn't get their hands on the actual ''Zyuranger'' Dragon Armor and tried to make their own. The problem is, Saban's piece is made of of shiny gold fabric, which looks completely different from the matte gold FRP original.
** It was actually explained somewhere that JDF told the producers he didn't think he could act well in the original shield, so after they originally replicated it, but had to remake it with cloth due to this reason.

*** Some fans felt that giving Tommy more angst at being forced into evil and making him TheAtoner could've given his character a bit more depth and made both occasions of him losing his powers all the more impactful. It is brought up on occasion a few times whenever Tommy gets brainwashed for the plot of the day or when an evil clone is made at one point but not for anything longterm and things are always back to the feel-good by the next episode.

* MistakenForRacist: It wasn't until ten episodes into the series that anyone from the cast or crew realized the implications of casting a black man as the Black Ranger and an Asian woman as the Yellow Ranger, but that was never the intention. Thuy Trang was actually a last-minute casting to replace the original Hispanic actress who quit holding out for a larger paycheck. Walter Jones was originally cast as the Blue Ranger. The producers wanted him to switch because the Black and Red Rangers were best friends in the Japanese footage and Jason and Zack were portrayed as such in the American footage. Jones agreed because he liked the Black Ranger costume better.

* FoeYay: Adam/Scorpina and Kimberly/Zedd is canon.

* RetroactiveRecognition: Before he was [[Series/MalcolmInTheMiddle Malcolm's Dad]] or [[Series/BreakingBad Walter White]], Creator/BryanCranston voiced several [[MonsterOfTheWeek Monsters of the Week]] on this show (Billy Cranston was even named after him). Even [[HilariousInHindsight funnier]] considering that he was cast as Zordon in TheMovie.

* FanNickname: As common as it is to see Doomstone referred to as "Doomstone," the name is never spoken by anyone in the episode itself. In reality, he's just a nameless tombstone monster.

** More specifically, the ''Green Ranger''. More than one kid's interest in the series tapered off after he was "written out" (i.e. he was killed off in the source material that MMPR got its sentai footage from) and replaced with the White Ranger, and even people who never got into the show at all still see him as a pretty cool character.

* GermansLoveDavidHasselhoff: The show aired in Japan via TV Asahi in the 1990s via Japanese dub and (English) subtitled version. Even though it aired late at night,[[note]]This was done so that its ratings wouldn't be taken from viewers watching other toku shows on TV.[[/note]] it was popular with male viewers in their 20s[=/=]30s and with kindergarten children.

** While quality-wise, many would argue that MMPR isn't the best season, popularity-wise it has stood the test of time. More to the point, the whole franchise as a whole proved doubters wrong in regards to them claiming Power Rangers was a fad that would die out along with TheNineties. It has keep chugging along with new installment after new installment since then.
** Season 3 is a slight case. It is generally perceived as the peak of quality solely within MMPR in terms of narrative, character focus, and having a serialized story arc, a quality carried over to ''Zeo'' and generally beyond. At the very least, many agree that if MMPR has to absolutely be emulated for nostalgia's sake, then at least future writers should look to Season 3, not Season 1.

* BigLippedAlligatorMoment: "Green With Evil" parts 3 and 5 are briefly interrupted by "Dance-offs"; the first between Billy and Zack and again between Zack and Alpha. (Some episodes of the first season had a little less than nineteen minutes of runtime, they had twenty-one minutes to use.)

** Likewise, at the beginning of the time capsule episode Billy is the one who personally hopes there won't be any prejudice in the future. This is painful to hear with the knowledge that David Yost would later quit the series because of the prejudice he was receiving from the crew in real life.

** After Creator/DavidYost coming out as gay, the parade of female love interests for Billy can feel like this. [[HarsherInHindsight When you learn the reason he left the show however...]]

*** In that same conversation, Ernie mentions that the Power Rangers do for Angel Grove what Batman does for Gotham. Him knowing of Batman's existence creates a bit of a mind-screw later on with the release of ''ComicBook/JusticeLeagueMightyMorphinPowerRangers''...

* TheProblemWithLicensedGames: Averted. The 16-bit games were surprisingly good. ''Mega Battle'', released in 2017 for UsefulNotes/XboxOne and UsefulNotes/PlayStation4, plays it straight; while it has its fans, it's generally considered to be mediocre. The Gameboy games totally stunk though, both having poor controls and overly difficult bosses.

* FranchiseOriginalSin: The GreenAesop that was widely seen as Anvilicious in ''Series/PowerRangersWildForce'' existed as early as this series. The reason people don't complain about it here, however, is that it was eventually toned down, not to mention that it was more presented as the rangers raising awareness, as opposed to a motive to fight the villains. While ''Wild Force'' isn't entirely to blame, since the aesop was a result of the show being a direct translation of ''Series/HyakujuuSentaiGaoranger''[[note]]not to mention that prior to the Animus arc, it was practically a FantasticAesop in the show[[/note]].

** Lord Zedd had to be toned down after the MoralGuardians deemed him too scary. As a result, he went from being a serious and scary villain to a comedy relief villain like Rita... [[SubvertedTrope except, not really]]. Zedd only seemed less badass in demeanor, but actually following the entirety of Season 3 and even into ''Zeo'', it's clearly a case of the opposite: He became MORE badass his schemes and forced the Rangers into constant defense, to the point of actually ''beating'' them.
** When Tommy was introduced as a villain, he single-handedly took down the entire team. After this, he was given more power ups with each episode that only served to make him weaker. Then Rita stole the Green Ranger powers, which were only restored through Zordon giving Tommy bursts of his own energy, which made his powers unstable and unreliable before they were lost forever. Then Tommy became the White Ranger. And all was forgotten.

* ''SugarWiki/MostWonderfulSound'': A rare evil example: Lord Zedd's voice is ''very'' [[EvilIsCool cool and intimidating.]]

* TheyChangedItNowItSucks: Lord Zedd was very scary when first introduced in Season 2. Too scary. So the executives demanded he be toned down to being a silly loser in Season 3, ruining the point of how dangerous the Rangers' job is. He did recover a lot of his original qualities mid-way through the season in the three-part "Changing of the Zords."
* TheyWastedAPerfectlyGoodCharacter: The Morphin' Masters, mentioned in "Big Sisters."

** Billy getting the most love interests out of the entire cast might seem HilariousInHindsight when you learn that actor David Yost is homosexual...until you ''also'' learn that some of the staff gay-bashing him behind the scenes (and nobody actually doing anything about it) was the reason he left the series. Not to mention that him having that many girlfriends may have been [[HaveIMentionedIAmHeterosexualToday a desperate attempt by the producers to have him NOT seem homosexual]] (even though he [[StraightGay didn't]]).

** After David Yost coming out as gay, the parade of female love interests for Billy can feel like this. [[HarsherInHindsight When you learn the reason he left the show however...]]
