Even though "Murderous Maids", as a title, sounds like an American sexploitation B-flick, this film tells the true story of a pair of French sisters who serve as house maids, make incestuous love with each other, and kill their employer. Set in 1930's France, this biographical film spends considerable time developing the characters so when we see their shocking behavior it seems almost understandable. With critical plaudits aplenty, numerous awards, and sterling performances by the pair of leads (Testud & Parmentier), there's little doubt this is a quality film. However, given the unpleasantness of the issues, a somewhat tedious build to the climax, lots of maid stuff, and subtitles for non-French speakers, one should give this film due consideration before committing to the hour and a half watch. Will play best with foreign film buffs and others into serious psychodramas. (B)
