A lot more amusing than I thought it would be.

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 not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

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