This was the inflamatory line "Forget honing your skills and mastering the craft of animation like those classic artists, just cheat your way into thinking you’re an animator by moving some crap around in Flash."
I will admit that I personally prefer hand drawn animation, but drawing and animation are not the same thing. Consider stop motion, or 3-D animation. Apparently some of the best Pixar animators can't do tradition animational. That doesn't make them bad animators, it just means they are not great draftsmen (or women). If you wanted to play devils advocate, you could argue that stop motion, 3-D, or any cut-out style of animation is more pure than hand drawn animation. Animation is movement, not drawing, so if the medium eliminates draftmanship from the equation, you can't hide behind nice drawings. Your work lives or dies by how well it moves.
And finally, in defense of moving crap around in Flash, check out this Yo Gabba Gabba music video directed by Justin Fines (who I don't know) and animated by Andy Kennedy (who is a good friend). You can do some awesome stuff in Flash by just moving crap around.
I'm hardly impartial, but I think this is the one of the best piece of animation I've seen done for Yo Gabba Gabba. The only other short that has impressed me as much is Nick Cross's "Kites Are Fun" piece.
Of course, what I like about Kites Are Fun, are the drawings and design more than the actual animation (which is still really good, and MUCH better than what his budget should have allowed, I'm sure), whereas what I like about Andy's piece is the animation more than the design. So the dichotomy continues!
