Grief is new

This has a bit of Groundhog Day and Memento feel to it. Christine (Nicole Kidman) is a 40 year old amnesiac. Every time she wakes up in the morning, her memory has been erased, but with a help of a video diary, her husband (Colin Firth) and shrink (Mark Strong) she begins to understand her past. In fact, a complicated, mysterious and thrilling puzzle begins to unravel. Flawed, but alright.
