Query: LURID AND SADISTIC

AMERICAN NIGHTMARE is one of those movies you wonder how it ever got made. Despite an interesting premise, the film basically exists to show a sadistic killer nurse castrate and murder a local hunk; torture and kill the heroine's sister; and even have the heroine shoot her sister assuming it is the vile killer. Yuk. And the radio program itself guickly degenerates into a foul-mouthed, lewd, ridiculously scripted farce. The movie never explains why the killer nurse is on the rampage; why she hasn't been caught; and then the big finale where we're supposed to go "Oooh...I never suspected that" makes no sense because no back-up is provided for this stupid ending.Debbie Roshon, the "star" of this movie, plays the role so convincingly, it makes me wonder if she was acting at all.AVOID AT ALL COSTS.
