Ghost Fuckers (2010)

Cash Markman's tale of a haunted house filled with the visages of former lovers swings from creepy to humorous and back again. The boy/girl (and 1 girl/girl) format of the scenes (no threesomes, no group sex, no anal) really makes you wonder why all that stuff is needed. The sex is hot. All of the performers have great chemistry (Roxanna and Cody Love fail to sizzle somewhat), and the voyeuristic aspect of the plot makes it stand out for more than just what it is.
