Unknown

All I can say is that if you are expecting Taken Part 2 you can forget about it.
Liam Neesom plays a man who awakens from a coma, only to discover that someone has taken on his identity and that no one, (not even his wife), believes him.
Unknown comes off at first like a Hitchcock movie with the audience totally engaged. Halfway through the movie slowly looses steam and meanders until you find out that the whole story is about something that you really don't care about.
Diane Kruger does a good job a supporting Liam but January Jones, the bitchy wife from Mad Men, is totally wasted in this movie.
There is not much more to say about the movie but Liam is great playing a tough guy but he needs better material.

Verdict:
Taken 2 is a no brainer. Just have Liam go save some other kid in a foreign country.
