I'd wager that, nine times out of ten, directors don't set out to make a bad movie. Nobody in their right mind wants to fail. Unfortunately (or quite fortunately, depending on your perspective), Uwe Boll has never been in a right state of mind.
A couple of years ago, a documentary entitled Tales from the Script was released. It gathered a number of high-profile and lesser-known screenwriters to share their industry experiences, and among the guests was Guinevere Turner, the writer of Uwe Boll's BloodRayne. She describes her time on the project and lavishes praise upon Boll for his pleasant professionalism and open development schedule...
Hell no! She can't stand the f*cker! She sent a first draft -- a first draft -- of the script to Boll in the hopes of gathering feedback for the necessary revision, but he was all like, "Nope! This is the tits! We're going with what we have!" Then he cut 80% of the material and had the actors fill in the blank space like a big ol' Mad Libs. I'm surprised that Ms. Turner could sit trough the interview without frothing at the mouth.
However, I'm wary of her final remark, as I doubt some people will appreciate the comparison.
