BAD SAMARITAN (2018) **1/2 David Tennant, Robert Sheehan, Jacqueline Byers, Lisa Brenner, Carlito Olivero, Kerry Condon, Rob Nagle, Hannah Barefoot. Decent suspense thriller with Sheehan's petty thief stumbling upon a victim-to-be of a serial killer when he attempts to rob the home and winds up in the crosshairs of an ultimate grudge match/cat-and-mouse with a few good jolts delivered and one box of crazy turn Tennant as the seriously f'd up creepazoid. Director Dean Devlin and Brandon Boyce's clever script combine for enough popcorn pleasing moments of meta-scream-at-the-screen scenes and even a few canny self-asides to aforementioned sequences.
