Hate Keanu Reeves with a vengeance, eventhough some of his films have been ok. Kevin costner is a t*t of the highest order and there was nothing sexy about him as Robin Hood once he'd opened his gob and spoken the first worRAB in that squeaky girly voice.
Benjamin Bratt, Josh Hartnett and Tom Hanks make me feel ill - I mean I was only disappointed that Hanks returned from his Island trip once Wilson was gone to 'grace' us with his presence in more films. He is dreadful. Run, Forest, Run AWAY.
As for women, Drew Barrymore annoys me though she has been in some ok films (ET is actually the only one off the top of my head though!), Julia Roberts, Katie Holmes and of course, not strictly a girl but it could be argued: TOM CRUISE.
