There is so much greatness in Your Sister's Sister, which I discuss further at Battleship Pretension, that I really, really hesitate in saying it's not worth your time. The performances are marvelous, and writer/director Lynn Shelton's ability to manage dramatic conflict, farce, character development, and improvisational comedy throughout the film's second act is really one of the most beautiful things I've seen all year. But when the film falls flat, boy does it ever. So if you're willing to roll around on some very uneven terrain, proceed to select cities this Friday. But tread lightly.
