Went to The Tara to see Martha Marcy May Marlene. Thoroughly enjoyed it, highly unsettling and wonderfully acted, though the writing for a couple minor/supporting characters wasn't quite up to the standard of the rest. The pacing was perfect, slow enough to allow the lead's character (and, just as importantly, the tension) to develop with genuine depth, while not so slow as to drag. Release is pretty limited at the moment, so if it's anywhere near you, make an effort to catch it.
