Funny, emotional, personal. 5 girls take a trip to London before 4 graduate and leave behind the fifth. K-on itself was about growing up, about the fact that lives moves on and you have to leave your memories behind. The movie is about when you have accepted that, but want to make a last memory, a last goodbye. The story of a last goodbye song to the person you care the most, Brings me to tears, every time.
Still no reason why this movie should be this good.
