“Samhain: A Halloween Horror Story” (*1/2 out of four) was an amateurish horror thriller about a girl (Michelle Moracco) about to leave for the West Coast who ends up housesitting on her final night in town; to the surprise of no one but her, a psychotic killer shows up and stalks her to the death. Writer/director Joe Gray lamely rips off “Halloween” in a few key shots and right down to some of its film score but there’s otherwise not much distinction here from thousands of other direct-to-DVD dreck. Film is only a little more than an hour long but no one will likely be complaining.
