Did you people see the same film I saw?

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 movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.
