Film would have been much better with a little explanation
I enjoyed this film quite a lot especially the style and story but I was left scratching my head throughout the whole thing.
But I just couldn't understand a few things, firstly why they were quarantined in a run down building without any help? It didn't even look like someone was being tested on to work out a cure. They just threw a bunch of blind people in to a building as though it were the last option and didn't even give them enough food, canes or anything that could help them. I can't understand why they would try and impoverish them in such a way or why they weren't allowed contact with the outside world.
Secondly, why were they just pooping and urinating on the floor? I know they are blind but they are not dogs. Surely the place had a toilet they could use. For that matter why were they just throwing litter everywhere and why did the kid piss himself?
Thirdly, why did the soldiers continue to guard a small group of infected when clearly most of the world was becoming infected and how did their blindness prevent them from opening the gate and going "hey, we are all blind now. You can leave".
