I always looked forward to watching K-On! every week. Like musume_no_hoshi said, it couldn't compare to God Knows, but it was still a good way to end the show. I always liked how light-hearted it was, and the animation was a remeniscense of a combination of Clannad mixed together. At times, I wanted to jump through the screen and give the characters a hug because they're all so cuuute
Although I'm used to watching lengthier series, I'll be looking forward to episode 13, and hopefully, a second season ^-^
