Davis is a disturbingly gifted emotive cartoonist. He knows something most others don't: how to make his characters ACT. And you get the feeling with him that, if he's going to put a lot of detail into panels, he's going to make it all meaningful. He doesn't put anything there that doesn't add to the meaning. Quite different from, say, George Perez or Jack Kirby, who were both very detailed but more because they just enjoyed jamming the composition with stuff. (which, BTW, I do not mean to call an inferior approach, just a different one, any more than paint is better than ink; I mention it only as a contrast)
