I believe what he is saying is:
Beast Man should be this scary, feral villain, but like you said, he was played for laughs too. They all were. But that was the nature of the series. If you look at the toy line from Four Horsemen, there was an attempt to make the characters look a bit more sophisticated.
I've taken that as part of my inspiration and am now making what I believe to be a story that is a nice sophistication of those old TV shows, which used the villains primarily for comic relief. It's slightly more serious but not without the same sense of wonder, excitement and fun the TV show provided to its fans.
