martha marcy may marlene

i've seen four movies over the past few weeks .. and this was the best one so i won't talk about the others .. although tintin wasn't that bad .. so martha marcy may marlene .. this is one dark movie despite what the name might suggest .. elizabeth olsen plays a troubled young girl who escapes from a cult and goes to live with her sister and her husband .. she is haunted by her past and afraid that they will come for her .. in other words she is a mess .. of course this means that she has trouble adjusting to life in the real world .. so basically the movie goes from scenes with elizabeth at her new home .. and scenes of her back when she was still with the cult .. and the ending .. well let's just say it's "unusual" ..
