Original and fun take on the whole medium/ghosts thing.
Starring that guy from Tucker & Dale VS Evil.
"Kevin Pacalioglu (Tyler Labine) is a lazy slacker, and a medium for hire, who attempts to solve various ghosts' unresolved issues, so that they can move on to a final resting place, occasionally with the help of his best friend and drug dealer, Roofie (Brandon T. Jackson)"
