Sometimes it’s okay to admit that you have no friggin’ idea what’s going on. For example, this trailer for “Weirdsville.” I don’t get it. The cast, however, entices me. Scott Speedman and Wes Bentley. To that I purse my lips, tilt my head and say, okay, let’s go see a midnight show and have some mozzarella sticks. It’s important to support the alums of ‘Felicity’ and “American Beauty.” I’m not exactly sure why. It just is.
