What makes it different from others?

Very interesting film. Was caught on the premise when seeing the trailer but unsure as to what the outcome would be for the showing. As it turns out, it was a very good film.

it is the rare 'crazy' movie that actually has something to say.

The movie is made so realistic it has a lot of that WoW feeling at the right moments and never tooo over the top. the suspense is done so well and the emotion is felt. Very well put together with the music and all.
