This whole movie can be interpreted in many many ways. But what's the point...it's just fun to watch. After I watched it...I went to IMDB or whatever...and people have so many theories. Like that there were never any crawlers. There was good evidence too...but why would you want no crawlers...those things were crazy, nasty little fuckers. I bet the director ddn't even think about it as much as some people do LOL.

As for the end...there were actually two endings shot. A UK release (the original) and a US ending. If you got the DVD in the US...the director actually merged the two endings. This leaves you will basically 'you decide what happened'. There's a special feature on the DVD that explains this. It was a pretty cool movie though.
