So other then a few people seeing a Mushroom Cloud far away in the distant, then people arguing over petrol till they spilt some... what actually happened? Also were all those kids on weed? They were the most docile kids I've ever seen in a car crash/Nuclear Warfare situation... not that I've seen them, but you get my point. 
  
Slow show that didn't seem to achieve anything in the hour it had, I was sitting there waiting for it to expand, for a character to be definded (other then the obvious hero figure), but nope, everyone seems to be the same character.
