Now that the currently airing anime season is wrapping up, the comments section of the site I frequent are talking about which animes need a second or third season.
The thing is, when I talk to my friends about sequels, they usually talk about how the first season was great, but the second season was a letdown. I don't have many expectations, and tend to think highly of most second-seasons.
But still, a second season, or third, or fourth, is better than no more seasons. So which ones would you really, really like another season for? It doesn't have to be from currently airing.
My personal votes go to Angel Beats, D-Frag!, Saint Onii-san, Seto no Hanayome, and Usagi Drop.
