My head says that good animation is good animation, whether its made with pencil and paper, computers, stop motion puppets, clay, bottle caps, or whatever.
My heart says hand-drawn animation. It's just the medium I find the most visually pleasing (though there's currently a Clampett Bugs in desperate need of dental work in the top banner who is trying to convince me otherwise.)
I like computer animation just fine. I liked
Kung-Fu Panda. Loved
Beast Wars and
ReBoot. I worship just about everything Pixar does. But if all you tell me about two movies is that one is hand-drawn and one is computer animation, I'll pick the hand-drawn one. It's the style I grew up loving, for one thing. I also really love to see evidence of the artist's hand and there's more of a direct connection between what the animator is doing and what you see on screen with hand-drawn than there is with computer animation or even stop-motion. You can still tell good work from bad and in any medium, the ideal is usually for the whole piece to look consistent no matter how many people are working on it. But with computer and stop-motion animation, everyone is using the same physical or digital model, while in hand-drawn, each drawing is individual and one character may be drawn by many animators, each putting their own ideas into their work.
Every style of animation has its own strengths and weaknesses and while computer animation has made leaps and bounds in recent decades, there will always be areas in which it can't match hand-drawn. Something that i frequently go back to it this argument is
these pencil drawings of the characters from Disney's Bolt. I ended up liking the final movie OK, but to my mind, a lot of appeal was lost in the translation to three dimensions. The simplicity of these drawings draws your attention to the detail that are there. As a drawing, Mittens immediately reads as a scruffy-haired alley cat. But when you can see every hair on her three-dimensional body, the effect becomes more subtle. (And if IMDB is to be believed, getting it to look right was a challenge.) This may not be the fairest comparison, since I don't feel like Disney ever fully got the hang of full computer animation (witholding judgement on
Rapun...errr,
Tangled.) But I think it demonstrates some of the aspects of hand-drawn animation that I particularly love.
If anyone actually wants to talk 3D (special glasses, images popping off the screen, etc.) vs 2D (most movies, no special dimensional effects, no glasses required), my position is much more definite. I prefer 2D. I do have a bias, since my eyes don't entirely focus in the same direction and only the most extreme 3D effect really do anything for me. I also feel like it's nearly always just a gimmick. It doesn't really add to the storytelling in most movies. You'll either have scenes that are put in exclusively to show off the 3D, or the effect will be so subtle that (most people I know tell me) you stop noticing it at all. The one good argument I've ever heard for 3D came from John Lasseter discussing
Up and talking about how the depth of field changes when the fog lifts and the whole landscape is revealed. That's at least plussing the storytelling a little, even if it's not an effect that I think would only come across in 3D. And I don't feel like I've missed out on anything big by seeing
Up exclusively in 2D.
