It presented them as naive, strait-laced, low-tech and in need of a good shot of rock 'n' roll to shake things up and get them moving. Yeah, there was a bit of nostalgic glow about it -- but I never caught any hint of actually wanting to get stuck there.
I won't argue that things took a hard right turn under Reagan, but contrasting the (very brief) upsurge of hippie/liberal themes on tv for a few years in the early 70s with the never-all-that-monolithic media of the 80s, seems disingenuous.
Here are 20 out of the first 25 films (excluding those dated 1980) from an online list of top films of the 80s. Granted these aren't the top-grossing films -- but except for Die Hard, I can't see much I'd label as explicitly conservative.
