It’s an especially fun movie from a director and cast who are clearly having a good time allowing themselves to let loose.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

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