Of course, malls in those days had bookstores. To-day I watched Friday's episode of Dantalian no Shoka, a show that has had persistently good writing but has rarely been as visually interesting as it is in the new episode.
The whole episode features fluid animation that looks like it was done in pencil on sketchbook paper as an indication that the characters have entered the world of a certain book.
I strongly suspect the episode had a guest director, maybe even Kazuya Tsurumaki as the animation and look of the characters reminds of FLCL and Top O Nerae 2. I'd like to see a whole series like this. This is the first episode of Dantalian no Shoka that really felt like a GAINAX series.
