I have mixed feelings about Soul Eater. "Doesn't take itself too seriously" is definitely a plus, I like the kinda goofy artstyle, but it does end up being pretty serious sometimes and I think that's where it takes a nose dive. Crona was a fun character but basically everything in the lead up to, and including, the final battle was srsbsns and made me cringe a bit. I feel like I would have absolutely loved Stein's character if he wasn't quite so much of a mary sue. Even when he was busy being conflicted there wasn't any doubt he'd come around in the end.
IDK, fight/action anime just rubs me the wrong way categorically and maybe the thing that bothered me about Soul Eater was that it flirted with being something other than that but couldn't commit to it in the end.
