Great paranoid premise just needs to ramp up the pace sooner

Rating: 7/10 (5 October 2013)

Dr Martin Harris (Liam Neeson) and his wife Elizabeth Harris (January Jones) get into a car accident. Martin survives but when he wakes up, his wife no longer recognizes him and someone else (Aidan Quinn) has taken his place. The world becomes a place of paranoia, and the only person who helps him is the waitress Gina (Diane Kruger).
It's an unusual head scratching premise. It's a mystery as to what the true story is. Is it all in his head? Or is it reality? The pace could be faster in the first half. I wish they didn't push the color spectrum so far to the the blueish green. It's obvious and distracting. Also they need to pair up Kruger and Neeson a lot sooner. As it stands, the movie is split in two. The first is a slow meditating paranoid interior film. The second half becomes a Bourne Identity film. It'd probably improve to concentrate the first half more.
