Re:Loving 80's music and movies
Yep, the pattern is to reject what has recently gone out of fashion and embrace things that are a bit older and have thus become 'retro'.
When I was a kid in the 80s, the most uncool thing imaginable was the 70s with their stupid hair, sad flares and crap music. In the 90s, the 80s were awful (though not to me, I always stayed true to them!). Personally I wonder if it's just to do with the age of the people who have control in the media. Right now the kids of the 80s are running things which is why we see things like Mr T in Snickers adverts.
