Iris sends her best friend, Jack, to her family's remote holiday cabin for a break. He is mourning the death of his brother who was also a previous boyfriend of Iris'. When he arrives at the cabin he finds Iris' sister, Hannah, there. They get drunk and have sex, an event which becomes problematic when Iris arrives the next day hoping to develop a relationship with Jack who then discovers Hannah wanted to become pregnant! Interesting plot but the film lacks momentum and doesn't contain sufficient drama or depth of character. The naturalistic dialogue and slow pace fail to produce a realism that appeals.

Sometimes there just isn't an aspirin big enough . . .If you're a love sick, lonely freshman, than by all means rent this with your dorm buddies and talk amongst yourselves in endless clichés about love and limits on love and on and on and on . . .For the rest of us, avoid at all costs.When I read that the actors ad-libbed most of the dialogue, that was all I needed to read in explanations about the dribble. I'm sure it was all meant to be profound, but it just came across as amazingly sophomoric. *** Potential Spoiler ***And what is it about films where some fat slob guy, with virtually no redeeming qualities still has a sharp hotties still want him? I live in the real world and I don't see that very often.

I finally caught up with Your Sister's Sister on DVD, a movie that reminded me of Eric Rohmer movies, more than any other recent movie. (In fact, the movie I kept thinking of is his "L'Ami de Mon Amie" - variously known as "Boyfriends and Girlfriends" and "My Girlfriend's Boyfriend". But this is not to suggest that "Your Sister's Sister" is derivative or is a lesser movie.) The writing and acting is superb, as is the ending. All three cast members are great, though Emily Blunt (she is great) may be somewhat miscast. And, watching this movie, I kept wondering why I don't see more of Rosemary DeWitt?Don't miss this one!

3.6 of 10 (temporarily rounded down until the film's rating is more realistic). This is what happens when you have some technically talented people (typically a group of actors and camera people making a film together based on a loose idea) in the details of film-making and no competent writer/editor. I'm guessing that's why some have been fooled into giving it good reviews. The gloss and general idea allows them to overcome significant story and casting flaws.We'll start with the title and sisters who clearly could only be adopted sisters (very different accents and face structures). Instead, they try to force them on us as actual sisters.As for the story, this seems like a romantic fantasy for inbreeding slacker hillbillies/Brits set in the Norwthwest. It hops on a couple of other current fantasies involving lesbians to expand its audience, but that doesn't really change the inner demented stupidity of the story. You could even argue that the writer does this with the intent of associating lesbians with inbreeding. Or the more likely scenario that the story was a raw idea made a complete mess by letting the actors go impromptu.I'd like to say a few post production edits could save this film, but it really requires a different direction in the second half of the film. Edits could make it less bad and maybe into an average "complex" film.
