As kids, my friends and I thought the Masters of the Universe toys were cool, but that the original cartoon was lame. We preferred shows like GI Joe, Transformers, Spider-Man and His Amazing Friends, Thundercats, and Robotech. Even the kid-centered Dungeons & Dragons cartoon was less kiddified than the Filmation Masters of the Universe series.
The 2002 series on Cartoon Network was quite good, though.
