Your Sister's Sister

This film is about a man who gets invited to a country house by his best friend, where he sleeps with his best friend's sister after a drunken night.

"Your Sister's Sister" is close to a single location film with a minimal number of characters. Most of the film takes place in a house with only three people. For a film like this to be good, either the characters have to be interesting, or the plot has to be emotionally intense. "Your Sister's Sister" is unfortunately neither. The plot lacks tension or emotional climax. It is just too plain to sustain attention or interest. Mark Duplass portrays an unlikable loser, and yet he gets all the adoration from the two sisters which is rather unbelievable. Rosemarie DeWitt plays a selfish woman, and she is not likable either. Emily Blunt's character is the only interesting character, but she is not enough to save the uninteresting plot or characters. It is unfortunate that "Your Sister's Sister" is an underwhelming drama, as it could have been a lot more than it currently is.
