“Grindhouse Nightmares” (0 out of four) was a nightmarishly awful bargain-basement collection of grindhouse cinema which make you remember why grindhouse theaters are all now out of business; in the first, a hapless jerk (Steve Munroe) is tormented by someone he can hear but not see; the second is titled “Stripper With A Shotgun” so you can probably infer what that’s about. Not even the faux-coming attractions in the middle featuring Michael Madsen are funny! For a more impassioned and funny throwback to grindhouse cinema, watch the 2007 Robert Rodriguez/Quentin Tarantino trash classic “Grindhouse” instead.
