Season 1 of Legends of Tomorrow was a mixture of tones and themes that ended with somewhat of a bad taste in the viewer's mouth. It wasn't sure where it wanted to go, it wasn't sure of what it wanted to do. It's ironic that the issues of the first season became a sort of metaphor for the show's characters: evolving beyond where they started to become something better.
Made up of the secondary heroes of the Arrowverse, the show painted its characters as outcasts of that world, not good enough to headline their own show like The Flash or Supergirl. The first season labels this mentality as a bad thing. After recognizing that the tone of the show wasn't working, the writers decided to embrace that theme, but with comedy being the end result rather than melodrama.
Thus was born a different show basically. Superpowers took a backseat to wacky situational comedy. Fistfights were turned into corny motivational speaks. And their characters evolved to fit this new paradigm. The strangest thing about all of it: it totally works.
Legends of Tomorrow is not for everyone, as most superhero properties are. However, this show from season 2 on is definitely worth a try simply due to the fact there's nothing else like it on air right now. They're may be no other show like it period. The incredible mix of corny action, the wacky situations the Legends find themselves in, and the genuinely good development of basically every character all come together in a truly remarkable story about people changing for the better.
I do believe what they say is true: heroes are in the limelight, they are the ones seen and their actions are praised. But the people you don't see are just as important. Heroes are the ones we remember, but Legends never die.
