I think about Bill Waterson a lot. I certainly don't blame Jim Davis for "selling out". He made a marketable character, and I don't blame him for trying to make his money because of it. I don't have a ton of artistic talent but if I created a lovable comic character and someone offered me a dumptruck full of money to sell toys and t-shirts and cartoons, I'm pretty sure I would take it, and I might even take it even i…
And as such, Garfield has never had any sort of message or meaning. It's just a cartoon that kids and some adults like.
Waterson, on the other hand, very obviously enjoyed his work and pushing boundaries. C&H was chock full of his personal beliefs, messages, and morals. And he loved causing newspapers headaches. He did things like purposefully making odd shaped vertical comics just to force the comics page editors to deal with and think about how they'd lay out the page. All to try and break people out of commercial thought, to make people question "why is the layout like this".
The two are such polar opposites it's almost amazing they both ran comics in the same papers.
I wish we had more watersons running things in all forms of media.
