Maybe it's because I saw it for free, but I found myself enjoying the darkness in this movie. I also understand that this is the second movie in a trilogy (at least, 3 with the similar story) and knew there would only be compounding of problems, not a clear villain and ending.
If you think there wasn't enough action, you need to re-watch it. Starts with the car chase, then a fist fight suspended in air, then another car chase, followed by a boat chase. Not enough action? The problems for me were the foreshadowing (mainly, the ending with the power source for that building). Other then that, I was satisfied with the film, and look forward to the next release.
