I wanted to see Martha Marcy May Marlene, after hearing Mark Kermode choosing it as one of his 12 best films of 2012, on Radio5Live.
I can see how it it being fairly unique, and not very derivative of many other movies could appeal to film-buffs.
It stars Elizabeth Olsen, who is on screen almost throughout, as an escapee from a sinister cult, led by a man called Patrick (John Hawkes).
We know nothing of her life before her two years with them, except that her sister is her only living family. She moves in with her sister, and her husband, at their lakeside holiday home.
Through multiple flashbacks we learn of some of the traumas that she's endured, and there's almost no story, except of her mental decline, as she and we try to figure out what's real and what's not.
It's faintly Ingmar Bergman-esque, and a few of the scenes slightly reminded me of The Strangers (2008).
It could have been both more suspenseful and less vaguely ambiguous, and there's little to enjoy in it, other than occasional unintentionally funny bits of dialogue.
However it's encouraging that funding can still be found for some Hollywood movies that are interestingly different.
