Sometimes less is more.

Rating: 9/10 (12 March 2017)

First off, I'm rating it 9/10 purely because there should have been a little more 'alien activity' rather than the last 5-10 minutes of movie.
Even though it was pure intense suspense from start to near the end, it worked a bloody treat because I was on the edge of my seat wondering what the heck was going on, what was going to happen next.. John Goodman made this film what it was, a terrifying feeling of something awful about to happen around every corner. I constantly thought aliens were going to find a way in to the bunker and wreak havoc, but nope, he comes across as a little bit crazy, especially to the 2 co-stars of this movie.
The score was perfect, cast and acting.. I don't think another actor could have had the same, or better impact on the overall feel of the movie. Definitely one to watch!
