blkmage, you are awesome and I am ever grateful that you organized this tourney.
2011 was a fantastic year, both personally and on a production front. I got back into anime right around this time last year, with Birdy the Mighty, and I am so deep I hardly believe I could get out now. I caught up on a great deal of things(my MAL was at 45 items when I started Birdy, and is now at 130 as of yesterday) and I got pretty deep into watching things as they air. My favorite anime of the year, as previously mentioned, was easily Mawaru Penguindrum, though the best movie was definitely the second Macross Frontier film. Some other favorite things of the year include Nichijou, Usagi Drop, Fate/Zero, Chihayafuru, and Madoka.
As for some of the other questions, the best character of the year was pretty easily Sheryl Nome in Sayonara no Tsubasa, where she is incredibly awesome. The best OP is another Penguindrum choice, for either of the OPs, though the Madoka and F/Z OPs were also great. As for EDs, I think the best will have to go to Fate/Zero, which has a very awesome ED. Best music was Macross, for obvious reasons, and I can't think of too many shows I was disappointed by, except NO. 6, but that disappointment also got me to watch Xam'd, so I can't even hate the show itself.
I think 2011 was a fantastic year, and it's good to see that three of the biggest hits were Madoka, Tiger and Bunny, and Ano Hana, all of which were original shows. I eagerly await more(and apparently Urubochi is giving us another anime later in the year).
