Martha Marcy May Marlene ★★★

Quite frustrating, really. The central performance by Elizabeth Olsen is exceptionally good, but I'm not convinced there's a whole lot of substance to the film itself. It really doesn't cover much in its 90-odd minutes beyond "girl is indoctrinated into creepy cult, girl escapes and is messed up". My overriding feeling come the final (deliberately and irritatingly) vague shot was "So what?"
