I like movies that are aware of what they are selling... without [any] greater aspirations than to make people laugh and that's it.

Although it has its amusing moments, in eneral the plot does not convince.

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.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.
