The problem is that in live action they try to emulate the anime looks. Some anime have amazing plot, that could make great movies or tv shows if adapted well, but when you watch something which
characters look that stupid, it's hard to take anything serious.
I can watch, without any issues, a drawn animation with spiked and colored haired characters, and I don't think they look cringe at all. They usually fit their animated world just fine. But if you're doing an adaptation with real life people, then please....... make them look and act like real life people in their daily lives instead of a bunch of cosplayers. It's this dissonance that makes live actions absolutely terrible. It's like the amalgamation of the worse of both worlds.
