  • Though the dialogue is mostly improvised, it feels rooted in the relationships as well as pleasingly spontaneous.

  • It's comforting to watching dramatic and comic fiction regarding the things some of us actually have to deal with in life. When done right, those kinds of films are worth your time. YOUR SISTER'S SISTER happens to be one of them.

    November 8, 2013 | Full Review…
  • Movies that start well and end badly occur often enough, and yet even knowing that is no preparation for what happens to Your Sister's Sister.

    January 8, 2013 | Rating: 2/4 | Full Review…
  • Deceptively meandering and unexpectedly complex, Your Sister's Sister combines a poignant, funny directness with a teasing incompleteness.

    September 6, 2012 | Rating: 3.5/5 | Full Review…
  • Duplass is wonderful but even he can't shine as brightly as Emily Blunt.

  • The film's conceits may be a bit too contrived and conventional, but nothing about these characters' interactions are forced. Your Sister's Sister is a welcome guest.

Audience Reviews for Your Sister's Sister

  • Dec 09, 2014
    Really damn good movie that subverts the typical rom-com tropes with a complex and unorthodox twist on the 'love' triangle. But really, I just found Emily Blunt to be absolutely adorable in this movie, hence why I rated this movie as highly as I did. Actually that's a lie. Emily Blunt is adorable here, but the film is really very good. The casting is absolutely tremendous. For a cast that only focuses on 3 characters for a great majority of it, you could not have asked for a better cast. Emily Blunt, Mark Duplass, and Rosemarie Dewitt compliment each other perfectly. I cannot complain on that front at all. If there was some improv here, then it was either very minimal or not particularly noticeable. I tend to think there was no improv whatsoever, with the exception of the scene where Jack and Hannah have sex and Jack, after finishing, squeals for some reason. Jack rapidly retorts 'sorry, I squealed' which made that moment somehow funnier. I think that's the only real ad-lib in the film, maybe I'm wrong. Plus, with the film's story being the way it is, it probably couldn't have been improvised for the most part. But the story is pretty damn interesting for the most part. These are characters all stuck at a crossroads in their lives. Jack, having lost his brother, has shut himself off from the world and just done nothing for a year, Iris being in love with her Jack, even though she used to date Jack's brother, and all that brings, and lastly Hannah getting out of a loveless relationship after seven years because she felt she couldn't wait any longer on her need to have a child. How all these peoples' issues come together is really satisfying and intelligent. This movie is, essentially, 90 minutes of people just talking and for someone who's reading this, that might sound a little boring, but it works. I was truly invested in this movie from the moment it began and it kept me hooked until it was over. Usually in movies, in general, you have this part, before the climax, where it just drags. This movie never drags, it's incredibly well-paced. There's also plenty of laughs, it's never truly laugh out loud funny, cause that's not what the movie is trying to do, but it's funnier than I would've expected going in. The comedy isn't really over-the-top or slapstick-y, it feels completely natural and organic. I know I didn't give this a flawless rating, but I'm having a hard time finding something that I may have disliked about this film. It's just really fucking good. And, despite the fact that it may have been an indie film, I think this does a good job at sort of avoiding the things that people may dislike about indie movies in general, and sort of find a happy middle ground. I think people who love indie rom-coms will love this and, while this isn't something super casual, it could also appeal to someone who's not particularly inclined toward this. It's a very hard thing to achieve, I would imagine, so props for that. As you can see, I was a big fan of this film. Thought it was really good and I regret not watching this much sooner. This is definitely worth watching.

    Just finished watching this and I was totally captivated by this unconventional drama. I hesitate to call it a romantic comedy. It is romantic, and there were moments that brought a chuckle, but this covered some pretty serious ground and did so in a way that really caused me to empathize with all three characters. It just about had me bawling at the end! And that, for me, is the best sign of all. I am leaning toward five stars, as I want to own this one. Fantastic acting by the three leads, beautiful scenery (I want to live there!), and some really great camera angles added up to a wonderful experience.

    Your Sister's Sister is a charming indie dramedy that veers into predictability in the last thirty minutes, but is still appealing and funny thanks to a good cast and very naturalistic believable dialogue. It's not exceptionally great, but it works well enough and a welcome change of pace from other much more derivative rom-coms.
