Yeah, I loved the Nelvana episodes, but DiC's were a lot more awesomely whimsical and surreal. Nelvana's felt a bit more like a normal "cartoon", for lack of a better term, and later on came up with every excuse they could to forget that the characters were, in fact, Care Bears. Even as a kid, I thought the Star Trek episods were a little much...
Though I love the character model variations they used for the "Food Facts & Fables" episode. Those could actually give the new series a run for their money in terms of cuteness.
