Your Sister's Sister
So.
"Your" is Jack (Mark Duplass), a wayward late-twentysomething who has no direction and constantly wallows in self-pity. His "sister" is Iris (Emily Blunt), his longtime best friend and requited but unconsummated love. Her sister is Hannah (Rosemarie DeWitt), who enters the scene when Iris sends Jack to a secluded family cabin in hopes of him finding meaning after a little "alone" time. Hannah recently split with her girlfriend of 7 years and has already taken up residence in the cabin. She and Jack bond over their internal agonies.
Unfortunately, Hannah and Jack end up sleeping together on their first night in the cabin. This causes problems with Iris arrives in the morning, hoping the time alone will lead to them working out relationship issues. While Jack tries to dance around their dalliance, Hannah's sinister motive is revealed.
"Sister" is self-indulgent. Every scene is purportedly impromptu, which does a good job of displaying the talent of Blunt, Duplass, and DeWitt. But the story and characters are so trite. So, so trite. Hannah's motivation is legally criminal, and Iris's subservience to the situation lacks any drama. Jack, the lead character, has an intoxicatingly stupid character evolution from irresponsible jerk to.. irresponsible jerk. The film tries to pass off his climactic decision as him becoming responsible, but it just isn't. It's not. It's him pretending to be responsible. It's so shallow.
Not to be too negative. The film does have likable performances. I actually picked this up out of curiosity about Blunt. Her role in "Looper" was one of that film's highlights, and I wanted to see more of her recent work. She doesn't disappoint. Duplass and DeWitt also play their roles well, riffing with wit and precision.
Oddly enough, the film's transfer is downright horrible. It must have been shot in fullscreen, because the widescreen Blu-ray decapitates characters in almost every scene. The first scene begins with Duplass monologuing...with no head. An odd creative choice.
The lone special feature is a theatrical trailer, which basically spells out the entire story. It may be better just to watch that on YouTube rather than the entire film.
