please don't read any of the following it's bullshit
yotsubato is a celebration of the medium in my mind. by that i mean i think it's at its best in the state it's already in. the reader-defined timing, direct creative control, the slickness, the brevity, the lapses, it's hard to transfer that zen-like wonder and restraint to animation. it would be so busy. for example i don't see how animating this sequence of mr. koiwai would be effective at all.
even azumanga daioh had an unconventional production, if you don't already know it was originally a 4 panel comic, and when they animated it they aired it in 5 minute blocks instead of a regular time slot which to me is the TV equivalent of, say, newspaper funnies
i guess my point is yotsubato is already the best it can possibly be
