To illustrate my point, from a previous post, about Bob Clampett's cartoons being extremely talky, here are two versions of the same gag. One is from Clampett's "The Great Piggy Bank Robbery," the other from "China Jones," a McKimson short from 1959.
Of course the first version is better, but then, you don't need me to tell you that McKimson 1959 is inferior to Clampett 1946 (or McKimson 1946 for that matter). The point here is that in 1946, Clampett has Daffy Duck talking through every step of the gag, telling us what he sees, what he's doing, why he's doing it, and making a smart-ass pop culture reference after the gag is over. In 1959, Daffy does the same gag without saying anything except "oops." And this is McKimson, whose cartoons by this time were the most dialogue-heavy at the studio.
I think the dialogue in the earlier version enhances the gag, honestly. Take the dialogue away and it's a straightforward cartoon gag from Warren Foster, a good gag (as his gags usually were), but there are a limited number of things that can be done with it. The dialogue overlays Daffy's bravado and misplaced self-confidence on top of the gag, making the payoff funnier because he so clearly had himself believing in his own brilliance.
I guess what I'm saying is: 1) Don't anybody get the idea that Clampett's cartoons are "cartoony" because of their pure visual style. They are cartoony, but they're some of the talkiest cartoons ever made, and talkiness is actually not incompatible with cartooniness. 2) Avoiding dialogue and telling the story in pictures rather than words does not actually make a cartoon more "visual," and can actually make it duller.
