Title says it all
I think people are underestimating this movie.
The title says it all its a stern warning for us all about nuclear weapons and imho and in light of the nuclear deal with Iran could prove to be rather portentous - I think it was done very well - Of course it aint gonna be all joy and whoop de doo and full of zombies - jeez man some folks really just want bubblegum for the eyes and ears!
Character development was poor though and could have done with better photography but apart from that its a tale well told!
