Huh... dunno, haven't watched some of these personally, but a few of them I find kind of odd cause I've never seen them included on a bad movie list before.
For example, A Walk In The Clouds. Never seen this movie, cause I'm not really into romance films, but I distinctly remember seeing a review for it on a Siskel and Ebert show (I think Ebert gave it thumbs, but I'm not sure.)
Let's see... Renaldo and Clara, Texas Night Train, haven't even heard of those two. Club Paradise? Sounds vaguely familiar... Seven Years In Tibet? With Brad Pitt? Er... again, haven't seen, heard it wasn't the greatest of films, but top 25 worst?
I know the list comes from a poll; I'd be curious to see the demographics of the people who voted.
