I remember some portions of Clannad were really well animated, the other world parts I believe. However its almost like it was TOO well animated, like it looked really bizarre. As if Kyoani were using too many frames to portray too little movement. The way everything moved just looked really weird, especially the way the girl's hair moved, everything was way too smooth. Are there any other cuts in anime that are....over-animated I guess?
