How bad is it? Deliriously tacky no-budget wonder.
Should you see it? Yes, if you can find it (VHS only). [see comments]
I missed this because I mistook it for "The Mutilator" (1983) or "The Mutilator" (1985). It's a regional film from Tulsa that's reminiscent of Don Dohler's work. An alien craft crashes into a house and the aliens go on a killing spree as a college class takes a field trip. It's surprisingly good-looking, shot on film rather than video and with a lot of fog machines and saturated colors. Then there's the effects, which are mostly stop motion claymation. There's a cheap synthesizer score, a digression about Mormonism (!), actors reading cue cards, blowing lines and underacting, cattle mutilations, an arm punching through a chest. It's puerile, but it's perfect for emptying the fridge of beer.
