While Disney and Warner Bros. are the kings of made-for-film cartoons, Hanna-Barbera are the kings of made-for-TV cartoons. The creators of The Flintstones, The Jetsons, Yogi Bear, and Hong Kong Phooey; they've all been successful, but the crown jewel of their creations is Scooby Doo.
Unlike most cartoons, Scooby Doo was a smart and ingenious creation that required thinking and deep thought. The adventures of four teen sleuths and their Great Dane have been a regular viewing pleasure for years. Heck, I still watch it today. The best episodes were the first ones from 1969-72. I think they got progressively better over time because in the early ones, they didn't have enough suspects; usually, they'd only meet up with the guy who was the criminal. Later, they'd have 4 or 5 guys who could be the one unmasked at the end.
As for Scrappy, the only episodes worth seeing with him were when he's with the full cast, solving mysteries. I liked him here, because the act with Scooby and Shaggy always being frightened of every situation got tiresome; at least Scrappy would go right in, and Shaggy and Scooby had no choice but to follow him in, or Scrappy would egg them on. Only when they didn't have the full cast and were only in comic situations (i.e. all the other shows) would the show be awful.
