House Of 1000 Corpses: I wanted to repeatedly beat Rob Zombie with a dead hooker.
Star Wars Episode 1: I screamed at the screen after it was over and vowed to let Lucas feel the Force of my foot in his ass if I ever met him.
Transformers 2: I could barely stomach the first, but the second one made me want to vomit from my EYES.
Titanic: best nap ever.
Eragon: Did not expect much...but it went out of it's way to insult me. There was a survey attached to the film with no worse catagory than 'Not So Good'. I handed the sheet back to the survey group and loudly asked the audience if they liked the film. Got a resounding 'NO!' I asked if they thought it sucked, got a louder 'NO!!' I then asked quickly (as I saw the ushers coming) what they would tell other people about it. Got statements mostly along the lines of 'Stay away". Then I got kicked out of the theater and given a free pass to a future film.
I could rant for hours why I disliked this film, considering my rating for it is a F**K YOU! I think I best keep it to myself before I get Nolanites on my ass about it.
