My favorite seasons of any superhero shows are DD S2 and The Flash S1, two shows on opposite ends of the spectrum and have little in common except for one thing: they embrace their comic book roots, and I love them for that. They’re about superheroes doing their superhero thing and not trying to hide or water down that fact.
I love JJ S1 just as much as well, but I see that less as a superhero thing in the traditional sense and as more of a psychological thriller. Same for Legion. I love DD S1, but it feels less unique to me as it basically felt like a superior re-do of what Arrow was trying to be, and the way they saved the costume until the very last (lackluster) finale gave the impression that they were one of those shows ashamed of their comic book roots a little, insisting on keeping things “grounded.” It was just a basic origin story stretched out over more episodes than it needed to be, albeit with pretty good writing/acting/action and a GREAT villain. But S2, with the Punisher, Elektra, and the supernatural element brought in by The Hand, felt like a pure Daredevil show through and through, which is why I prefer it. And I never cared about the Flash in comics til I saw the show, but S1 of that show (once it got going, which again, episode counts are a problem) captured and embraced the pure comic book-y whimsy and escapism I get from a lot of my other favorite DC comics in a way no TV show ever has, so it managed to make me a fan of the character and his world in the process.
All that said, I think we're still a long way off from superhero TV reaching it's potential. My dream superhero show would have the comic book-y whimsical, optimistic spirit of The Flash (because let's be real, my dream superhero of choice would be Superman), the quality of writing/directing of Daredevil/JJ/Legion at their best, have 10-13 episode seasons and the budget/production values of Game of Thrones. Until someone's willing to make that kind of massive investment, the genre will always be held back on TV, imo.
