Earlier quoted context omitted.
I thought you were going to say something about how C&H made more insightful comments than jokes, but then you praised Garfield. Not to jump on the Garfield-hating bandwagon, but it isn't really in the same category.
They both have a tigered cat in them, so they seem very similar to me. The humor is also kind of the same, in that nothing really happens and the actors just stand around staring into nothing for frames on end. It is supposed to be a witty comment on the absurdity of daily life (they both also seem to convey the message that food is all that matters). After about one frame or so, it becomes boring.
in C&H its a stuffed tiger who and other aspects are imagined by Calvin a 5 year old kid. Calvin's interpretation is very smart and we can always relate to his thoughts. Often Calvins thoughts give us food for thought unlike in Garfield.
That explains why we can have a animation movie on Garfield adventures for kids, i am not sure it will be so easy with Calvin.
