Day of the Wacko (2002)

It is a bitter story about a middle-aged man, who hates his life and other people, including himself. Adam Miauczynski, the character known from director Marek Koterski's previous films, is a 44 year-old teacher, who reads poetry during school lessons and later goes home swearing and calling his neighbours' names. The worst pain for him is the next 5 minutes of living. He doesn't accept himself and even everyday contacts with others cause his aggression. Though constantly dreaming of a romantic love, he is not bold enough to make his dreams come true. The desperate Miauczynski personalizes our own fears and obsessions, which have become so visible recently.
