Well, I can honestly say I was very surprised. Many will complain it's slow, I will agree that it is, indeed. If you like "Timecop" type flicks you'll be better off skipping this one. I like the approach it takes on the meddling with time lines and I love the aesthetics of the "science" and machinery in it. I thought that maybe, from the critics I had heard, I would be bored of watching it after as little as 15mn but here's the thing, I didn't. It's one of these movies you have to try for yourself. If you start it, do finish it. In the end, I feel it's worth it once you go beyond its pacing. Even that improves dramatically in the end. Not a popcorn flick, rather a brainy type of time paradox movie.
