Reviewers are harsh to rate it so low when only the last part is blah. True, if you only care about the destination and not the journey, and you've seen a lot of similar movies you might be disappointed. But it's a very well done thriller and worth watching nonetheless. Apparently a lot of people expected what happens, but a lot didn't so your mileage may vary. I did, and while I wish they found a way to blow my mind in the end, I'm not going "oh I'm so smart, you didn't stimulate my superior brain, your movie sucks" and I just enjoyed the ride. Kinda like re-watching a movie you like, you know what's coming but it's still good.
