He's a completely insane horny man that loves action movies. His games tend to be high quality and even when they aren't good they are at least entertaining and try something new.

He may have gone full George Lucas at this point though where he's so overhyped that no one second guesses him at all. Death Stranding had some weird shit even for Kojima. I wonder what he could make if his personality wasn't so dominant in a game and it had some input from other creative visions to reign in his weirder ideas.
