Brian Landis Folkins looks so broken in “Rent-A-Pal” it’s a wonder he’s actually in one piece. His body sags and his face sinks, eyes sulking under a pair of glasses. He’s playing David, who’s somewhat of a loner. For a long while, all you really know about David is that he lives with his mother Lucille (Kathleen Brady), who has dementia. Also, he likes VHS. Every night he plops himself on the couch to watch the latest from Video Rendezvous, a video dating service in which potential matches communicate via VHS cassettes–think Tinder but in 1990. When he doesn’t get any matches, David turns to a new tape called Rent-a-Pal.
