The only negative thing about this film is the person that brings popcorn to it.

Rating: 9/10 (23 April 2018)

Sometimes we just get really surprised. We go to a film, expect a lot and go home displeased. Other times however, we go in expecting garbage but then fill up 9 or 10 stars on IMDb. If somebody told you there was a horror/sci-fi film that Jim Halpert directed and starred in, you'd be rolling on the floor laughing. Well, this is that film, except you gain a new respect for this man. It is a true success story for John Krasinski and his entire cast. I was awe-struck by the performance of each actor. The directing was foolproof; you could tell that every small detail was taken care of. It gives off the feeling that a perfectionist was behind it. And the action, the drama, the suspense, the sound... just brilliant. There are a couple of questions surrounding the story and the monsters that IMDb reviewer @jef_olsen touches on very well, but I am only removing 1 star for this as everything else was truly magnificent.
Seriously, the only thing I can really complain about is not even about the film itself, it's about the noise made by people in the movie theater. The reaching for and chewing of popcorn during the long, silent portions of the movie, or the passing of candy packets from one friend to another. And then there is the occasional 'Sally Soundtrack' who needs to be shushed a few times before he/she quiets down. If you're going to watch this movie, I highly recommend watching it at home, in a dark room, with 5.1 surround sound, no interruptions and absolutely no outside sound. Like many reviewers wrote, this is an experience, not just a movie. It has to be watched in "a quiet place".
