Number 1 Worst Film Ever has to be a dire Wim Wenders film called "Until the End of the World" which dh chose because he said the bands on the soundtrack were good. What a load of pants that was!
I fell asleep before the end of "Big Fish" and thus far haven't been inclined to see what I missed.
I hated American Beauty (so shoot me!)
Gave up on Donnie Darko (whaaaaat was that about?)
Pretty much anything with Jim Carrey in.
And I saw Dogville at the weekend - am still making my mind up on that one - very, very odd film.
