I haven't watched the main K-On! Series, so I was not really familiar with the characters and it took a while to get attached to them. There's not much of an overarching storyline in this film and it emphasises lots of cute moments like asking a turtle to decide their vacation destination. Most of the film is about snacks, tea, the girls trying to write a song for Azu-Nyan in secret and a London tourism advert. It was a lovely and heartwarming experience but I was left hoping for a bit more.
