The film doesn't show physical destruction of buildings, and has some inaccuracies. For example, people are driving cars, and they wouldn't be operable after an EMP (electromagnetic pulse) associated with a nuclear blast.
The music score by Henry Russell is rather post-romantic.
The full film can be rented from YouTube for $2.99 or from Netflix subscription.
