I love his involvement. When I make movies, I want to be as hands-on as him, doing all my own directing, editing, soundtrack, etc. And he always looks so cheerful and energetic. I just wish he would take off the bandana/hat a little bit more often at all. I want to see more of his hair. I love his hair.
From Dusk Till Dawn is my favourite of his movies, Once Upon A Time In Mexico being a close second. And Desperado is great, although that was primarily because QT did the super-cute cameo. I was a fan of The Faculty forever before I knew who Robert was, although somehow I didn't seem to pick up on him and do some research into his other movies, and I usually do that with most directors.
