I suppose there must have been a few things that happened during the 1970's that weren't completely hideous and cheesy, but I'm not here to talk about those things.
There's a fantastically corny, hopelessly dated movie called Rock-n-Roll High School, featuring the Ramones. Add that to your Netflix, and tell me: was this ever cool? Or was it ironically cheesy? I can't tell. How do you explain a seventies-style gymnastics/Ramones montage?
