How this movie rated so high is beyond me

Rating: 5/10 (6 May 2007)

I saw the rating of this movie here and thought i was in for a great ride, only to be extremely disappointed, the whole premise of this movie just makes no sense whatsoever. It starts great, lots of suspense and a very believable storyline. After the halfway point however this entire movie turns into one cliché after another which is very frustrating.
It seems that the entire second half was just a rush to the finish with no regard for the viewer. The acting was fairly average however they just seemed happy to be in a movie which was the impression i got.
All in all not as great a movie as rated here in IMDb, though can take up the time if you have nothing else to watch on the weekend.
