A film featuring lesbian incest and violence could easily descend into a sensationalist mess. This film avoids such pitfalls and is exceptionally good.
The atmosphere throughout the film is extremely dark and is absolutely fitting for such a disturbing tale. Very rarely do any of the characters smile. Tension, guilt and suspicion are present throughout. Most of the film takes place in dark interiors and even the outdoor scenes are marked by grim weather.
There are only four significant characters and all are splendidly written and acted. The direction and design are very strong. Very sensibly, explicit sex and violence scenes are avoided to allow concentration on character and atmosphere.Particular commendation should also go to Stephen Warbeck for his melancholy, sparse, music which fits the action perfectly.
This is a notable film in another respect. No male character is seen at all - there are a couple of male voiceovers but otherwise this is an exclusively female performance. This is a bold move, but very successful. "Sister My Sister" should certainly appeal to any discerning viewer who appreciates thoughtful drama.
