I liked 10's. Most of the shows you people consider average there would be fucking big and great during the early 00's. Shows were either decent or unwatchable back then.
It had more shows about working adults than the previous decade, liked Working!, Shirobako, Sore ga Seyuu and Girlish Number a lot.
Madoka made an huge opening for other shows with the formula of "maho shojo going dark", I liked it.
Ikuhara was more active in this decade that the past 20 years, although Penguindrum is still his strongest work.
2010 had Katanagatari, Panty and Stoking, Yojouhan Shinwa Taikei, Sora no woto, Durarara.
2011: Madoka Magica, Steins;Gate, Tiger & Bunny, Usagi Drop, Mawaru Penguindrum, Fate/Zero.
(mentioning Guilty Crown / Blood C for fun shitposting time)
