I've mostly read interviews with him and he's abrasive, dismissive of reviewers, aggressively doesn't care what people thinks and hate movies who feed you meaning down your throat. Doubt and self reflection (especially on his own hubris) is in no short supply for him though and he'll often back and forth on big questions (notably Rampage has two edits, one leaning more in favour of capital punishment, the other against), saying radically opposed things depending on the interview (he alternates between praise and loathing for the sort of cops he depicted). He certainly loves to be provocative and a contrarian.
