I can review Sayonara Zetsubou Sensei without even watching it, just by typing the character names
Itoshiki Nozumu
Fuura Kafka
Kitsu Chiri
Komori Kiri
Tsunetsuki Matoi
Kimura Kaere
Sekyutsu Maria Tarou
Kobushi Abiru
Hitou Nami
Fujoshi Harumi
Otonashi Meru
Those are some great names there. I can't even begin to explain why though.
