Very well executed

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

The acting is good, and the firecracker script has some excellent ideas.

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.
