I think Panic in the Year Zero was a pretty good film for it's time and place in history. (IMHO)

Ray Milland's "...social and political views " shouldn't matter any more than Oliver Stone's JFK (a dramatic interpretation) was made invalid by Stone's own political bent. Watch the movie for what it is; a SCIFI about a family coping with the A-Bomb and survival in a world that is quickly losing it's civility.
