LOL I barely recognized half of the names you listed, guess I'm getting old! Anyway, Kristen Stewart strikes me as the most miserable Hollywood personality ever. I would never, ever sit through a movie that has her in it. And Keanu Reaves has always irritated me and has ruined many otherwise entertaining films. Horrible excuse for an actor.
I think that most SNL alumni are terrible on the big screen - Amy Pohler is awful, as are most of the guys. Will Farrell gets on my nerves, David Spade isn't funny, and there is one guy who is just horrible but I can't remember his name.
Who else? Tori Spelling, Jennifer Aniston, Goldie Hawn and her daugther whose name I can never remember, that annoying and unfunny crass girl from There's Something About Mary whose name I can also never rememeber...the vapid, blond, dumb as toast, anorexic one...
Richard Gere annoys me, as does Kevin Costner. Oh and Jennifer Lopez.
