I loved this movie. It reminded me of the early 2000, R-rated or silly Will Ferrell comedies that don't get made anymore. It's a whodunnit with some suspenseful moments but all comedy. LOTS of sex jokes and potty humor so that might offend some people. I couldn't stop laughing. There's some serious bangers on the soundtrack and more than a few hilarious songs.
The ghosts were unique. The depiction of the afterlife was interesting; I don't think I've ever seen it like that before. Bart the demon was my favorite character! He was an annoying little dweeb who constantly tried to trick the ghosts into going to hell. It's seriously crazy. Don't watch with little kids but definitely watch with a group for the best time ever.
