I know he's a unbelievable shitbag but I love most of David O Russell's movies. And I really loved the box officer failure (and middling in terms of the movie criticism), I Heart the Huckabees. I didn't love it despite it's pretentiousness. I loved it because of it. And the ridiculousness of the philosophical underpinnings between connectivity and nihilism right in the middle of a national ad campaign for a department store. GENIUS.
I also liked Bubble Boy but that was a terrible movie. So I won't expound on it.
