Intriguing thriller but too many plot holes

Rating: 6/10 (30 April 2016)

'Unknown' is a decent enough thriller that keeps you interested and guessing until the end. The story has potential but is ultimately let down by some far-fetched scenarios and plot holes.
In the opening few scenes alone there's one coincidence too many - Dr. Harris forgets his suitcase, crashes into a river on his way to retrieve it (after a container falls off the vehicle in front), and is then saved by a taxi driver who goes on to risk her own life (again) to help him find out who he is.
I can't say that I didn't enjoy 'Unknown', it was a good 2 hours of entertainment, but it would have been a lot more enjoyable if it was believable too.
