Before I Go To Sleep (out Oct 16) is the story of a woman with amnesia. She wakes up each morning with no knowledge of the previous day. Why is she like this though? This is a curious thriller where she suspects that not all around her are being truthful. I wasn't fully convinced by the performances and didn't think there was enough material for 90 minutes... but a few twists and the broad nature of the mystery kept me interested. Grade: B.
