I'm happy I didn't listen to the bad reviews here and skipped this movie. It's very well made.
And yes, it raises more questions than it answers, but this is how it would be during an apocalypse or cyber attack. You wouldn't know what's going on and wouldn't trust anyone fully, you could only rely on some bits and pieces of information.
It wasn't boring at all, very engaging actually. The fact that most questions that come to mind when watching it are not answered, leave you thinking about what you would do and even question things in life you take for granted.
This movie is only uncomfortable for those who don't wanna use their imagination and own thoughts and expect a movie to put every answer in their mouths.
I haven't seen such a thought provoking, elegant yet unsettling movie in a long time!
Oh and by the way... the big question everyone has, what's actually going on is answered at the end, just pay attention to the conversation in the car and the computer screen.. It's all there..
What happens after? Well, finally a movie that allows you to use your own thoughts.
