Cold Fish (2010) Shion Sono

When Syamoto's teenage daughter is caught stealing, a generous middle-aged man helps resolve the situation. The man and his wife offer to have Syamoto's troublesome daughter work at their fish store. Syamoto soon discovers the horrific truth of the seemingly perfect couple.

This film is impossible to fit into any neat category. Its part horror, part black comedy (its extremely funny at times), part serial killer movie, with a huge dollop of allegory about business and Japanese society. And its also a hoot - brilliant acting and direction keeps you hooked as the film gets gorier and gorier. The entire cast is compelling as a group of seemingly ordinary people who are teetering on either side of major personality disorders. And its not always clear who the real psychopaths are. Only the fish seem normal.

This certainly isn't a film for everyone. But if you enjoy a black comedy and have a strong stomach for some very realistic looking gore, then this will certainly keep you distracted.
