No spoilers as of right now.

This movie is disturbing. Let me just say that. If you don't like movies that are gruesome, I wouldn't suggest this. Was it really scary?
NO it was just disturbing.
I can understand why Rob Zombie had to re-shoot some of the scenes. Apparently they warned him and told him it'd be NC-17 (No Children under 17, no exceptions) and that's a kiss of death for the movie.
Still a neat movie.
*edit* I do believe that Sheri Moon who plays "Baby" in House of 1000 corpses is Rob Zombie's special "lady friend".
