Director-cowriter Seidl cleverly juxtaposes images, cutting between the stories at all the "wrong" times. For example, following a school teacher (Jirku) from a graphic orgy into a garish shopping mall, then to her empty house. The film is strikingly understated, but the camera work is telling and often startling ... which is the same way you'd describe the storylines and performances. It has the feel of improv; earthy humour and raw honesty express feelings of frustration, pent-up desire, dull routine and, above all, coping with the overwhelming heat. And the characters are all intriguing even though they're profoundly unattractive for a variety of reasons. Yes, this film is hard to watch at times. But it's an eerily accurate look at how harsh a society based on the individual can be.
