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 neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

Ok... Let's be honest. It cannot be the best movie but is quite enjoyable. The movie has the potential to develop a great plot for future movies

The film's masterful storytelling did its job. The message was clear. No need to overdo.
