I was born in 1973 so I remember the golden age of Saturday Morning Cartoons well. What's up with all these live-action shows now for kids that are little more than sit-coms and soap operas starring kids? Hannah Montana? Wizards of Waverly Place? Come on. The old cartoons is where its at. We lived in the country and only got three channels on antenna, so I watched NBC, PBS and ABC (when it wasn't too staticy). So I mainly saw cartoons like Smurfs, Strawberry Shortcake (my sister's two favorites); He-Man, Spider-man and Friends, Justice League, Droids (I loved that show and wished it hadn't been so short lived), Ewoks, Inspector Gadget, Looney Tunes reruns (never got old), The Real Ghostbusters, etc.
When I'd go to visit my grandma who lived in town, we could see more channels since she and Grandpa had cable. They had Disney Channel which showed all the classic Disney cartoons and USA had some great cartoons like Danger Mouse, Teenage Mutant Ninja Turtles and Rocky and Bullwinkle. TBS had all the reruns of classic cartoons like The Jetsons, The Flintstones, The Great Grape Ape, Godzilla etc.
I think of all the shows I saw, I probably liked Justice League and Spider-man the best. Though the Looney Tunes shows never failed to make me laugh.
Since I've "grown up", I've seen a few newer cartoons I like too like Batman the animated series and Samurai Jack. I've also discovered some great anime like Robotec and Appleseed.
