When you go see an Anderson film, you have a pretty solid idea of what you’re going to get. The mood, character development, cinematography, quirkiness, and pretty much everything else is largely the same across his films. I think this is obvious (?) to most people. Yes, there are individual differences between films, but I don’t think my opinion is an uncommon one.
There are more genres than action and superhero. A whole world of cinema, in fact. So it would be great if Anderson took his formidable skills and tried something new. A selfish request from a viewer, sure, but I just never feel like he’s trying to improve as a filmmaker and is merely doing what is comfortable to him.
