“The Happytime Murders” (**1/2 out of four) was a moderately amusing black comedy set in a world in which puppets and humans co-exist and a disgraced former cop and puppet (voiced by Bill Barretta) must re-team up with his former partner who is still a detective (Melissa McCarthy) to solve a series of murders when the former cast of a puppets television show begin getting killed one by one. Raunchy comedy directed by Brian Henson (son of Jim Henson who was the Muppets creator) is fast-paced and entertaining although not quite as hilarious as you might hope. McCarthy is good and seems to be more-or-less playing the same role she did in “The Heat.”
