Excellent, Without a doubt!!

It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

It's a mild crowd pleaser for people who are exhausted by blockbusters.

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.
