“Slice” (* out of four) was an abjectly unfunny horror comedy about a city pizza deliverer who is murdered on the job and various politicians and cops (Joe Keery, Chris Parnell, Katherine Cunningham, and others) search to find who may be responsible and they soon discover it may be a long-lost ghost or a disgraced werewolf (are you laughing yet?). Lame writing and direction sinks this all the way. Witless movie barely has enough material for a 10-minute SNL sketch and at nearly two hours may make you want to slice your throat.
