K-On's is very different than the others admittedly. Basically follows that show's more comedic slice-of-life tone, but does it very well. The production is very good though, especially in the middle, and I like how they enhance certain character themes from season 2.

Great to see this getting so much praise. Right now, my top tier for anime movies based on shows I've seen are Cowboy Bebop, Haruhi Suzumiya, and K-On, and I was hoping this would be right up there. I may have to wait, but am really excited to watch it.
