What makes it different from others?

It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

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.

One of the worst ways to make a cult movie is to set out to make a cult movie.
