The trailer really freaked me the first time I saw it... not knowing why it was those people were dissapearing (was she crazy? a dream?..) though, I wonder if they give too much away. I'd suggest not watching more than 2/3rd of the way in.
anyway, looks like it'll be a good movie. hope the preview isn't better than the movie..
