I didn't know much about it - and really enjoyed it. Ending could improve (some ideas)
My wife and I just watched this movie. Didn't know what else to watch and it just popped up on Netflix' homescreen.
We didn't know anything much about the story. But we enjoyed this mix of thriller, sci-fi, end-of-civilization. It is pretty slow paced and lots of questions unanswered. But it was gripping, it kept us guessing and going. And the cast did a really good job all around.
I don't mind some questions were unanswered, let's you fill the gaps yourself (e.g. where are all the people, why did the airplanes hit at that exact spot on the beach twice, who's behind it etc.).
Only the ending I felt was left to open. Or too positive. If I would have had a go at it I might have ended it like this:
Bacon, Hawke and Mahershala Ali all die in a shootout fighting over the meds. Myha'la, Charlie Evans and Roberts are hit by another sonic wave (radioactivity??) and it effects all of them, all dying over the next few days.
Only the character Rose (Farrah Mackenzie) is making it. I would keep her getting into the house, eating the snacks and finding her way into the bunker, turning on "Friends". But instead of ending here, a shape/person is getting in the house, into the basement and finally the bunker where Rose is watching Friends. In a flashback it is shown that it's the person coming all the way from the shed (where he/she was sleeping in the leafs) into this building. That person closes the bunker and locks it from inside. Rose is still unaware of the visitor. Fade to black...
