Are American tv shows stuck in Act 2 for their entire runtime between season 1 and final season?
Season 1s are great, setup, some payoff, a bit of lead into the overarching story. Then season 2 to X. The heroes win and then lose in the final episode, cliffhanger to next season. People get bored. Final season is announced and they wrap up the show.
I'm not sure what you mean by that, but it's a banger cartoon with amazing characters that comes full circle in such an immensely satisfying way. Top tier animation and writing.
