I gotta admit. Looking back, I don't think I liked most of anything from the 1970's. I've said this before, but cartoons were a wash in cloning Archie or Scooby Doo (who, incidentally was intended as a knockoff of the Archie in its earliest incarnation), cartoonifying pointless fads du jour (CB Bears), and sitcom based cartoons be they legit (Jeannie, The Brady Kids) or flavorless knockoffs (the Oddball Couple, The BArkleys, etc).
In that era, Hanna Barbera, Filmation, and DePatie Freling made some pretty lousy stuff. Though there were great things like Fat Albert and Hong Kong Phooey.
When it comes to eras in animation, I especially loved the 60's, the late 80's, and most of the 90's. When Fox and WB were starting up their own kids networks, giving the main three a run for their money, that was amazing. I remember three programs I loved being opposite each other half the time.
I really hope this is just a slump in animation history, and not the end of it.
