Hardest poll for me in some time. I went with Cruising...but I had to struggle with To Live and Die in LA and Sorcerer (which I had the pleasure of seeing on the big screen last year). Those three films are just consistently amazing. The only films I haven't seen, and the only two I don't own are Deal of the Century and Rampage. The man is one of my favorite directors. He has some great television credits, too, including a great Tales From the Crypt.
