I like that this comic strip has so much intellectual depth while still maintaining a theme that is interesting and works well as a children's comic strip. Hobbes has an immense amount of depth as a character, he is a living breathing person. Calvin and Hobbes as a whole is my favorite comic strip ever made, it can hit you and make you feel terribly, terribly sad. and then in the next panel have really quite clever humor. It can make you think, and then be something you can zone out to, it's art, and genius at the same time. It's a shame that the artist is dead, it's also a shame that this era of comic strips is also long gone with him.
