I love John Landis, and I love that he at least tries to do something new whenever approaching the horror genre. No one else would try to bring together the mafia movie with the vampire movie. And while “Innocent Blood” stumbles in to a messy, dull, and silly horror comedy gangster picture, Landis is at least courageous enough to try to see where it’ll all take him. “Innocent Blood” suffers mainly from being so self congratulatory, to where Landis almost seems to be patting himself on the back at times. There are myriad scenes of characters in the movie watching classic horror movies on television, which is distracting considering the movie is set in Pittsburgh during the winter.
