Training montage with the Rocky theme playing, not five episodes of them agonising over what it is that's holding them back, only for them to then repeat that process after the current villain is defeated and the next villain has presented itself. When my characters have to get stronger, I like a I like my plot arcs to end before I've had enough of them. I like my battles not to drag on for five episodes. Since my younger days of pokemon, digimon and yu-gi-oh (back before I'd even heard the term anime and just thought of them as cartoons), the longest anime series I've watched was 50 episodes, and that was only one show and took me forever to finish. I don't usually go for long running shounens.
