SIDEWAYS star Paul Giamatti has stopped checking out his films at the cinema because he can no longer watch them without criticising every scene. The actor admits he just grumbles his way through films these days - because his acting expertise has turned him into the worst moviegoer on the planet. He explains, "I stopped going a couple of months ago. I can't really watch a movie and enjoy it particularly anymore. "I'm sitting there thinking, 'It was really cold when we shot that,' or the level of his drink keeps going up and down, the continuity is off. "I can only see things like that. I know some of these people now and go, 'Oh, that guy's an asshole,' so I just don't enjoy it very much."
