I forget where I read this, but someone else put it best when they said one
of the most shocking things about this anime is that it contains NO
romantic, or dramatic elements. It is a lot like Seinfeld in that it is
mostly about the girls making observations and commenting on their daily
school lives. The character design, writing, and voice acting is top
notch. There are a ton of funny and interesting characters.
IMO, Azumanga and Abenobashi (maybe Tenchi) are the only two noteworthy
anime this season. The rest is trash like Tokyo Underground or fancandy
like Chobits.
