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 thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
