Amidst all my hype I'm nowhere near a position to judge, but why do you say that?
The main complaints I've seen are its OST, which, as is only natural, fails to live up to the games', the animation, which is nothing stellar, and people also express concern for the pacing and whatnot, as there's many cases to adapt. It'll be two cour, but that is still a lot of cases, unless some are skipped.
Personally, I had no issue with the animation and I didn't expect anything from the OST in the first place. Can't really judge pacing from the tutorial case, which was, as should be evident, shoved out of the way quickly.
I'm all for the ridiculously cheesy OP, too.
