You have a good point, but cartoons are universal and have been popular for a long time, not only with Disney and Warner Bros., but also Hanna Barbara, and MGM. Puppets have had some popularity, but it went beyond that when Jim Henson came around. My point is that no one can duplicate what Henson did.
I, myself, would one day like to start a puppet company and have my group of puppets just like my hero, Jim Henson. No matter how I may try though, I will never be as great, or even good as Jim Henson. Nobody will.
