If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

what a terribly boring film. I'm sorry but this is absolutely not deserving of best picture and will be forgotten quickly. Entertaining and engaging cinema? No. Nothing performances with flat faces and mistaking silence for subtlety.
