Rob clearly had a lot of fun with this picture, and not just with the cameos by Alice Cooper and Iggy Pop and Henry Rollins. The "band is travelling" sequences are stop-motion animation with miniatures because, I dunno, why not. Rob has a lot of fun with fast-motion and weird color corrects and such.
Oh, and Malcolm McDowell's the vampire hunter. Complete with a series of flashbacks to 1970's Malcolm McDowell, by cleverly editing bits of some 1970's Malcolm McDowell movie. Nicely done, Rob.
And, oh, the movie is funny. And stylish. And funny:
From the guys who brought you Epic Movie, Date Movie, Meet the Spartans and possibly the worst movie ever made, Disaster Movie. Your review makes it sound good, but it's currently sitting at 3% on Rotten Tomatoes and the lineage doesn't excite me in the least.
@Tim: You're thinking of VAMPIRES SUCK (2010). This is SUCK (2009). 7.0 on the IMDb. 57% fresh on Rottentomatoes.com (not every critic likes rock musicals about vampires).
