You guys DO realize that most of the HB cartoons that came out in the 60s-70s were just Scooby Doo or Flintstones ripoffs right?
Yeah there were a few good shows here and there (The Flintstones/Jetsons, Yogi Bear, Scooby Doo, etc - basically the company's flagship products), but once you take those out of the equation, you have mostly low-budget, poorly animated ripoffs of your most popular franchises.
So that leaves Peanuts. I grew up with Peanuts as a kid and enjoyed it (both the comics and specials). I still enjoy reading the comics and watching the specials now. Even if the jokes and gags are reused over and over again, to be fair, the Schultz wrote 50 years worth of comics, so a few jokes were bound to be reused at least 10 times or so.
Maybe its just me, but I could go either way with the HB or Peanuts theming. Today the only part of those that kids are exposed to are the TV specials for Peanuts and Scooby Doo/Flintstones for HB anyway. The Nick license is pretty much the only thing that would appeal to kids the most and even then, KD never really went all out with it (it was pretty much just the Rugrats car ride, the Space Surfer, and the slime/water maze).
