Yes, he is, because generalizing modern criticism is stupid and out of touch and directors getting mad at a poor reception and calling every critic "out of touch" has been the go to move since 1950.
You haven't read a critic in 15 years? Anyone reading the comment section has read a movie critic. Everyone with a pop culture podcaster they listen to has a critic in their ear. Maybe he should be listening to the professionals too because he hasn't made something good since JoJo in the first place.
The reality is he's not dealing well with not being those critics' quirky darling and he's lashing out.
Shit, you dumb old bastard, do you think the same thing about the critics who liked it? Or are the only good critics the ones who like everything you do?
