It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

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.

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
