Dementia 5

This Sin City series has director Jim Powers attempting to thread a difficult needle: deliver outrageous gonzo XXX content while maintaining an artistic, professional and stylish sensibility. It's almost impossible.

For the fifth edition he uses a familiar format: Otto Bauer brings his beautiful 18-year-old daughter to Tory Lane's Institute for training. It's a tradition in his family: his wife was trained there by Tory's mother.

The training is in sex from the BDSM school, giving the movie a starting point similar to that of the classic French tale "Story of O". For the following two hours, Tory and her staff put young Brooke through the ringer, far beyond the usual training of a sub which has become quite mainstream with the popularity of the "50 Shades" novels.

Powers is adept at high-energy gonzo porn, and both Tory and Brooke perform it well, with anal-sex, d.p.'s, forced-sex and various fetish stagings. Back home Bauer performs a ritual, saying a pre-meal style prayer at the dinner table and then having his way with stunning newcomer Gabriela Rossi, nude and lying where the food should be, for a threesome with Bauer and his butler Steven French.

Dana DeArmond is terrific in her latex French Maid costume guiding Brooke through an IR outdoor foursome with Black studs Brian Pumper and Nathan Threat. And a strange 5-girl lesbian group-sex scene is loaded with strangeness as four beauties including greats Diana Doll and Angelina Valentine womp on Brooke.

Throughout, Tory is in command, and overacts almost humorously as she over-enunciates Powers' less than deathless dialog in the pompous set-up scenes with Bauer.

Even the BTS is interesting for a change. It documents a serious flareup on set early in the shoot as the original leading lady freaks out and has a high-octane argument with Tory, resulting in the actress walking off the set and out of the film.

Powers replaces her with Brooke, and apparently it's smooth sailing from there. The lady's face is obscured to protect her identity but twice we hear her called Maya, which with a matchup to her revealed nude body on display establishes the actress as Maya Hills -and her side of the story of what went down is obviously missing.
