This film has a good look (seen it last year.) The story, about a group of protectors that can affect reality, unbeknownst to the lot of the world, to keep the balance of good and evil on level grounds. Of course, they are countered by the DayWatch (the second film is named this, and it out soon on dvd in russia.) who represent the evil side of things. The Nightwatch goes about trying to protect a particular boy who just may be the foretold messiah-like figure that they have been waiting for.
As I said, it had a good look, but it sort of bogs down towards the end. Might look pretty nice on a big screen though, and I would probably see it again to give it anothr chance.
The DayWatch trailer is online, but on a russian site. If I find it again, I will post the link...
