Worst movies you've seen

Rare case of the movie being better than the book (IMO) - The Constant Gardener. Awesome movie, quite good book.

Also, I could never get into the LOTR books. Call me a heathen, but I found the style rather boring.
 
Wow, this thread has generated quite a few posts, rather quickly!

I read the first LotR book, but it took a fair fucking effort to get through it.

Films are very rarely as good as the books they're based on; they'd need to be 5 hours long to capture the whole story in most cases.
 
Ooh how could I forget the steaming pile of shite that is sSweet Home Alabama? I saw it on a plane a while back. Why does Reese Witherspoon get involved in complete rubbish like that?

Euro Trip was funny in parts, but pretty shit for most of it.
