Cool and surprising I was super curious to see this movie as I am a huge fan of the movie Cloverfield. By mistake I thought that this would be a sequel - and I had already heard all kinds of rumors about what "Cloverfield 2" might be about.
What I got was different - but still pretty cool. The beginning pulls you right in, everything is just very intense and confusing - just as it would be if you were in the protagonist's shoes.
Speaking of the protagonists: I was extremely impressed by the understated way Mary Elizabeth Winstead carried the movie, and
I have to admit that though I'm not a John Goodman fan by any stretch of the imagination, he worked out great as prepper Howard, probably better than anybody else could, because his more than solid physique makes him appear as a broken man as well as intimidating at the same time.
The tension in this movie never lets up, not for a minute, and without wanting to spoil anything: The teasers are very adequate in preparing you for what this movie has in store - and then some!
