Scripts based on improvisation are garnering my respect as the best way to direct actors: it makes them sound more natural and more human than ever - and that is exactly why this film is brilliant. With a mesmerizing trio of performances and a set of smart directing decisions and techniques, Your Sister's Sister is a nowadays masterpiece, proving that intimate movies can be as excellent as any other. Five out of five
I think that there is an element of farce in the central idea behind this film. Aside from that it is played reasonably straight and makes for an enjoyable lighthearted film. I thought it was well paced, well acted and featured some beautiful scenery.
A good performance by Mark Duplass, but fell frustratingly into the category of "heterocentric-white-people-problems", in which the male is permitted to be of average attractiveness if he is smart and self-deprecating, while females must be thin and beautiful (personalities need not apply).
The first 2/3 of this movie were perfection: funny, realistic, dramatic, moving. But then once we find out the "twist" and it divulges into a terrible montage, I felt that Ms. Sheldon didn't quite know what to do with the characters once she put them in this situation.
The first half is a beautiful and tender portrait of everyday human relationships with 3 wonderful leads (Specially Rosemarie DeWitt. I love her) But the second half gets bogged down by a boring montage that feels more lethargic than cathartic. Still... the first part is amazing!
