I started out very disappointed in this movie, after it was hyped up pretty good by a friend of mine.  While the first portion of most movies is setup and character building, the build up went on way too long.  The first half of the movie at least.  We had to pause the movie to go do some Christmas stuff and when we got back to the set we decided to watch a SciFi Channel presentation that I was currently recording instead of returning to the movie.

Once my girlfriend fell asleep (she's sick, poor thing), I finished watching the movie by myself.  That's the point it got interesting.  Things started to happen -- I mean literally.  The movie started to actually get some action sequences and some interesting scenes as well as things moving and going bump-in-the-night on screen.

While I can't say that I shy away from spoilers in my opinions, I think I'm going to hold out any mention of what occurs at the end.  Don't skip forward to the last 2-3 chapters of the movie.  After you have seen it all the way through once, you could probably miss the first 5-6 chapters after that.  But the ending by far makes up for the slow start.

Have fun.
