It was OK. I thought it would be much better than it actually was. There are a lot of action sequences that help keep the movie "moving". There were many opportunities to delve down into and expand plot line - to really bring out the mysteries and lore that surrounds the central idea - but that was completely overlooked.
Like i said, if a storm is passing through, this is a good way to stay warm and dry, otherwise, wait for the DVD - much cheaper!
