Me and friend watched it a few days ago and we both liked it. We knew beforehand that this was part 1 of 2 and that the first movie is more of a build-up/setting the scene for all the action in the second.
If one knows nothing about it and expects a high-speed action movie then they will be very disappointed. This is more like the latest blade runner movie with great atmosphere, nice panoramas and soothing music.
We will definitely go see part 2 also.
