Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

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.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
