All wet but none too scary, “Lake Dead” is a derivative low-budget horror pic in which the usual RV full of well-toned L.A. bodies drive to the countryside, where they have a date with death via ax-wielding lunatics. Tastelessly crude inclusions of rape and incest would be more offensive if the whole were upsetting rather than, often, unintentionally funny. After Dark Horrorfest entry will be making a quick exit to DVD Land.
Alerted to the death of a grandfather they didn’t know was alive, three sisters vent rage at their estranged dad (Dan Woods), whose past track record as a jerk suggests he deliberately withheld this family connection; ergo, they ignore his frantic warnings not to go to the rural motel they’ve inherited from Gramps. The adoptive bad-girl sis goes up early, meeting a grim end. The others follow with various boyfriends and gal pals. Two hulking inbred brothers start winnowing this guest influx, and it turns out the sheriff is in on a fiendish scheme to use surviving sisters for breedin’. There is gore and T&A, but perfs, action and dialogue are sometimes sublimely dumb. Tech aspects are fair.
