Was far from what I expected, a must-watch for thriller and sci-fi movie buffs alike.

Rating: 7/10 (11 May 2019)

Was quiet long, but intense. John Goodman did an exceptional job at playing his character (Howard), as expected and couldn't have done anything more to improve it. Mary Elizabeth Winstead also did a good job, which came as a surprise to me, because I had never seen her playing a lead character in any of the movies I've seen her in before.
Climax & Ending: as a sci-fi fliek with a cryptic storyline and an almost perfect ending, I think the movie took waaay too long to get to the climax - as we actually got to see some action, short as it was, towards the end and the audience finally got some answers on what really happened above ground. And although it was short, I can honestly say that the ending was still unexpected and was probably made like that deliberately, so as to set the stage for a sequel.
The movie is a perfect example of how quality acting, storytelling and execution from the cast & crew will always beat fancy gimmicks.
