Before I Go To Sleep is a ridiculous movie. Frustrating and strangely predictable. It's a thriller about a woman who wakes up every morning with no memory of who she is or anything from the past. She is living with her husband who must remind her of her life every day. She starts keeping a video diary to help her remember and things become sinister as she questions the identity of her husband and the circumstances of the accident that led to her amnesia.
It's slightly gripping but sort of annoying. You want to figure out what's going on but the twists here and there get in the way a little bit and it's hard to care about any of the characters because the plot and concept dominate.
