Season 2 of One-Punch Man is giving viewers exactly what they want from every other shonen fighting anime. Where Season 1 brimmed with ingenuity and passion, Season 2 plods along with standard and tired tropes one expects to find in other series.
This is a sterling example of a brilliant premise milked poorly by inexperienced or dispassionate production. But... it's exactly what a lot of other, very popular series do. Excessive, time-wasting dialogue. Extended filler scenes. A dragging story.
I don't focus on the fight scenes in this review because I get that the level of animation from S1 demanded pure passion or huge funding, and that's not necessarily the fault of the animating studio.
Should've and could've been cut to 6 episodes. Everything would have improved markedly if most of the fat got trimmed. There's at least one high-quality moment each episode that redeems the viewer their time watching. But that's a lot of coal to scrounge through for a single, small diamond.
