How do people NOT understand this movie? * Spoiler alert *
I've been reading the different postings regarding this film and I am amazed at how people these days want everything spoon-fed for them. If you actually paid attention to the film as you watched it, and listened to the dialogue, you would have found that everything is explained very simply. And yet some people compalined that it was "too complicated" of a story.
It was a simple ghost story, with a sub-story about a shy, awkward guy who was attracted to the rather difficult girl. Within the film, all the characterizations are explained, and what happened and why. The guy was not a stalker, and the girl was more stuck in a "need to be cool" mindframe than anything else - with a lesson to be learned by the end of the film. He didn't know how to approach her, and figured he would offer a ride. In the film he even mentions how he would have "done it differently" if given the chance. I shouldn't need to explain anything about the ghosts because they are all explained in the movie. Somehow though, this fact is missed by quite a few posters on here.
And yes, after she realizes what's she's lost in him, he guides her back to civilization.
I think this is a fantastic movie that is filled with just enough suspense, eerie settings, and a very basic story (or two) that harkens back to the classic days of ghost story telling. If you didn't "get it," then I recommend you go back and watch it again.
