Nightmare Fuel: The ending of issue 3 where Brandon has burned off Utopian's face, killing him.
2021 Live-Action Series
Alternative Character Interpretation: Sheldon. Is he a genuinely honorable and idealistic hero who needs to work on his communication skills, or is he an arrogant and self-righteous control freak who cares more about a set of rules than the well-being of others? The fact that he can't seem to remember civilian names of his fellow heroes, implies that he only sees them as heroes and not humans. The fact that both his wife and his daughter tried to talk to him about how they feel, only for him to turn it on them, implies an unwillingness to see other's perspectives. In episode 8, Sheldon himself admits that he needs to learn how to listen more.
Base-Breaking Character: Sheldon/the Utopian. On one hand, he is a charismatic leader who's ideals lead to the age of superheroes and the creation of his world's Justice League. On the other hand, his ideals are too high and his high expectations of his family and comrades have lead to them becoming broken or disillusioned with him. He can be headstrong and flies towards danger, but he also tends to not listen to how this affects his loved ones. A running theme with him is trying to balance his high ideals with the human feelings of those around him.
Raikou, the psychic ninja played by Anna Akana. Given the popularity of Psylocke and being portrayed by a popular Youtuber, this was a given.
The therapist that Sheldon sees in Episode 5 for being a relatively positive depiction of a mental health worker, by analyzing Sheldon's obsession with the Code, processing Sheldon's feelings towards his father's death, and providing commentary on what the other people in Sheldon's life may be feeling. His reveal as Jack Hobb may or may not have helped.
Fandom Rivalry: Millar earned a lot of ire from DC Extended Universe (and Snyderverse) fans when he tweeted a ponderance if anyone ever finished watching Man of Steel in addition to a few other negative posts about those films over the years and agreeing with others who did the same. Said tweet unfortunately was posted mere days before Netflix declined to renew Jupiter's Legacy for a second season. Not surprisingly, this was mocked.
Harsher in Hindsight: Utopian's and Brandon's conversation about the latter not having Eye Beams becomes this when you remember Brandon killed him by shooting lasers into his skull.
Once Original, Now Overdone: Many of the unfavorable critical reviews pointed out that the questions the series asks about superheroes were not only addressed more skillfully in other shows thathad been released prior to it, but have also been asked by numerous releases of both the Marvel Cinematic Universe and DC Extended Universe. Therefore, ideas that might have been new and interesting when the comic first debuted merely come across as retreading old ground with less skill than its on-screen competitors. Even at the time of the original publication they were pretty well-trodden themes in comics, but the fact that multiple shows featuring similar ideas (morally-ambiguous Superman Substitute characters, intergenerational issues, the question of how superheroes would work in "the real world") had just received a ton of press turned Legacy into an also-ran for even a casual audience.
Special Effects Failure: Is pretty much littered throughout the entire show. From laughably fake effects to downright cringeworthy fight scenes, the effects in general look like they were made by a YouTuber rather than a professional studio. Especially considering that the budget is $200 million for the entire first season.
