Well, I watched the 25th episode of K-ON!! today, season 2 is almost over, but to be honest it felt to me like it ended a few episodes ago. I remember laughing every 5 seconds in the 1st season, and it was the same for half of the 2nd season, but it kinda went downhill after that. If there's going to be a 3rd season, I really hope they pick KyoAni steps their game up and not just throw some random stuff, as they did halfway through season 2.
Overall, my favorite character was Yui, she's just ridiculously dumb and funny in her own way. Also, she has the same electric guitar that I have. Yuh!
I am really looking forward to seeing the band members all grown up and in college :D
