Blood Countess 2: The Mayhem Begins (2009) - Lloyd A. Simandl

Review by Vallaor (courtesy of imdb.com):
“Blood Countess” is a sexpolitation movie that can be viewed as a part of the recent trend, trying to resurrect the legend of Elisabeth Bathory. This Hungarian aristocrat from XVII century, infamous for her sex crimes, was in fact one of the first well-known serial killers in history. Together with Vlad Tepes, she became the prototype of the vampire figure. In the classic Hammer flick she was even called “Countess Dracula”.

Vyhnání z ráje AKA Expulsion from Paradise (2001) - Vera Chytilová

Description: The uncompromising director Věra Chytilová, well-known for her harshly mocking attacks on people's failings and foibles, has created a new filmic parable on human weakness with Vyhnání z ráje (Expulsion from Paradise, 2001), her most recent film. Although fully within the Chytilová tradition of biting moral fable, the film has had a lukewarm reception from Czech and international critics.

The main story of Vyhnání z ráje concerns Rosta, a film director (Bolek Polívka), who is shooting a film at a nudist beach.[2] Everyone in the film crew has different ideas about the genre and style of the film being shot: The director tries to create an artistic work, an experimental metaphor about Adam and Eve; the Russian producer Igor (Milan Šteindler) hopes to see an erotic lovestory produced; and the screenwriter (played by theatre director and dramatist J A Pitínský) aims to express his positive philosophy about humanity through the film.

Svatá Ctverice AKA Holy Quaternity (2012) - Jan Hrebejk

Marital fidelity can wear you down, and Ondra (Hynek Čermák) and Vitek (Jiří Langmajer) are certainly suffering from a case of serious fatigue. Working side by side and living next door to each other, it doesn’t take long before these two long-married middle-aged pals start comparing sex notes, and it’s plain to see their latest scores have fallen far below what they would have hoped. Luckily, a surprise holiday on a tropical island rekindles their interest in their wives — only they don’t exactly lust after their designated partners. With no one to divert their attention, their roaming eyes inevitably settle on the wrong spouse, and pretty soon they’ve established their own little Holy Quaternity. The new film from Jan Hřebejk, director of the Academy Award®–nominated Divided We Fall, is an observant and audacious look at the measures some couples will take to revive desire. Ondra and Vitek’s irrepressible joie de vivre makes it impossible to pass judgment, even when the two couples break their own rules by fooling around behind each other’s backs. Parents to two sets of hormonally charged teenagers who endlessly circle each other in a clumsy pre-coital ritual — Vitek has two girls, Ondra two boys — the adults soon put their kids to shame by secretly straddling the fence that divides their communal front yard.

Six outwardly average individuals have elaborate fetishes they indulge with surreptitious care. A mousy letter carrier makes dough balls she grotesquely ingests before bed. A shop clerk fixates on a TV news reader while he builds a machine to massage and masturbate him. One of his customers makes an elaborate chicken costume for a voodoo-like scene with a doll resembling his plump neighbor.

Her husband, who is indifferent to her, steals materials to fashion elaborate artifacts that he rubs, scrapes and rolls across his body.
