The values implicitly promoted by the movie are definitely conservative in the extreem. I'm glad it's so popular.As for the movie being backed by "Republican" interests, I could care less. I really doubt it though, events back then have little to do with today. These people really were fighting for "survival". Survival of their history, culture and to ensure their children were not made slaves. Fighting for that and fighting for money, oil, and pimping out business contracts to rebuild bombed out countries, are pretty far removed.
My 17 year old son and his friends have all seen it multilple times. They went twice within two days!
