Good concept, poorly executed.

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.

Excellent characters with emotional depth. My wife, daughter and granddaughter all enjoyed it...and me, too! Very good movie! You won't be disappointed.

Worth seeing just to witness how winsome it is.
