There's always some, aren't there?
Queen of the Damned by Anne Rice, definitely, that movie was atrocious to say the least.
I Know What You Did Last Summer...I still say that was a rotten thing for the producers to do to Lois Duncan, since they had to have known that her own daughter was brutally murdered, and what do they do? They take a fine suspense piece where only one person dies and turn it into a hack and slash free for all film.
Dracula...I like Bram Stoker's story, I did not care so much for the Bela Lugosi movie...now Nosferatu I liked, but that's a bit of a different matter altogether.
Already I'm drawing a blank here, so does anybody else have some suggestions?
