I was excited to see this movie and disappointed. It starts off at high speed with all this dream stuff and it's like learning science while chasing the teacher down the hallway. I guess I'm not as bright as I thought I was because it took a third of the movie for me to follow what they were talking about. If there was an existing "dreamwalker" science to anchor to it might have been better. The special effects were good and I started to get into it after a while. If you don't need much of a plot premise and only care about freight trains running through the streets, go for it. I want my money back.
