Went to see it last night. I would put this in the category of 'good, but not great'.
I also would not compare it to the Matrix so much as to Dark City...a lot of similarities in the feel and the visual tone. The ending is rather predictable, but the overall production values are good.
Unbelievably, they used almost no CGI. I can't say any more without spoilers...but its worth the theater price of admission.
