Sound of My Voice (2012)

Atmospheric and spare film about an aspiring documentary filmmaker infiltrating a cult led by a woman claiming to be from the future. I was on the edge of my seat for most of it.  But, although I usually applaud movies that leave a bit of mystery -- those that refuse to tie up neatly just for the sake of doing so -- this one left me a little unfulfilled.  I really wanted to know.

B+
