Am I Missing Something?

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

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.

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
