Lacks a good ending

Rating: 5/10 (22 April 2018)

There's a really good ambiance construction throughout all the movie. The use (or lack of) sounds, voice and communication is really intriguing and very well exploited by John Krasinski.
Thing is, as soon as momentum begins to build, the movie ends. Could have extended the frightening experience for the audience, as it end comes in a very unexpected and thoughtless way.
