Best piece of music?: Not sure if I have a favorite. I love some of the stuff from this video:
Best song? (Note: Song, not tunes): I love all of them, but I'm gonna go with Connect by ClariS.
Best witch?: Hmm probably Gretchen.
Best episode?: Episode 10, hands down. So much becomes clear, and it was one of those episodes that bump up your appreciation for the show. Also, the feels
Best Drama CD?: Haven't checked those out, so I can't say atm. I'll check them out sometime soon since I hear they're quite good
Best movie?: Only seen the third one, so Rebellion. I plan to watch the other two at some point, though. Probably when Rebellion comes out on DVD, so I can spend a day watching through the three movies.
Best support/side character?: Probably Madoka's mom, since she gave Madoka plenty of advice and was just a good character in general. The other supporting characters didn't really do much at all. The show was really centered around the main characters.
Best scene?: I can't choose, since there were so many great ones.
Best ship?: Sayaka x Kyoko is OTP :3
Best friendship?: I really liked Mami and Kyoko's friendship in The Different Story, but when it comes to the show I guess I'd say Sayaka and Madoka.
Most tragic character?: Homura. You just feel so bad for her sometimes especially after seeing episode 10. Sayaka was quite tragic as well.
Best power/weapon?: I like Homura's time abilities the most, I think. Time stuff is always cool, and it's really badass when she uses all her guns and bombs.
Best Madoka game?: Never played any.
