>Worldbuilding, interesting and dynamic characters, deep lore which is not the main part of the story but a nice addition, good humour, god tier main villain, nice soundtrack, good-looking action scenes.
>Main character's personality isn't that well developed, Jinmay feels like a wasted potential, too many filler episodes, not enough backstory for important events of the past, animation mistakes, no ending.
>Season 5 comes out, has high-quality animation but the same voice cast, ties up the loose ends and romantic subplots, we learn the answers to all the important questions, ends with an epic battle and self-discovery for the MC. Jinmay becomes an actual part of the team. Everyone completes their story arcs. The ending is happy yet kind of bittersweet (they finally kill the villain and save the planet, but the Alchemist is now 100% dead with no chance of bringing him back, ever, and the evil will never disappear completely, so they still have to risk their lives on a daily basis).
>Season 5 never comes out. Instead, it's a reboot done in bad CGI with all the designs changed. We have to sit through nearly the same episodes, with new VAs and CGI, only for the show to mess up the continuity and introduce an annoying supporting character who becomes part of the main team. Jinmay is still underused, all the spotlight goes to the new character(s). The monkeys get an entirely new backstory for some reason. Romantic subplot with Sprx and Nova never moves past tsundere stage. Skeleton King is replaced with a new villain.
