I’ll go first. Mine is that I can’t stand the Deadpool movies. They are self aware and self referential to an obnoxious degree. It’s like being continually reminded that I am in a movie. I swear the success of that movie has directly lead to every blockbuster having to have a joke every 30 seconds
Not unique to anime, Hollywood has been remaking movies and TV shows ‘for a new generation’ forever. Anime is just following the same pattern.
It occurred to me why The Wiggles have been making so much money for so long: they only need to have enough material to entertain kids for a few years, and the ages that they’re targeting are the ones who love repetition anyway! Most entertainers need to constantly improve and evolve, but kids entertainers just need to enthusiastically do the same thing over and over.
I think one of the differences (at least when I watched anime way back in the early 00s) is that anime relies on a whole different set of tropes from Western movies and cartoons, and those tropes are unfamiliar (or were, anyway) to Western audiences.
When I started watching anime, it was hugely refreshing to be caught by surprise by plot twists and dialogue, and to see characters & themes that felt totally original.
But then you watch more anime, and realize…oh, they weren’t unique, they were totally stereotypical. You just didn’t know the stereotypes they were based on.
And before long you can see plot twists a mile away, the characters are predictable, and you can describe a new series as “basically X, but with some Y and monsters instead of robots”.
It’s the false promise of that initial discovery that makes the eventual realization that much more disappointing.
