Everything, and especially the mundane things, are animated so beautifully. The whole movie is just beautiful, of course this includes the soundtrack.
The ending was satisfying too. If 5cm's ending was more bitter than sweet, then this ending was more sweet than bitter. The progression from Takao's confession to him yelling at Yukari to her finally speaking out to the parting and then when he left the shoes at the pavilion was so perfect. It goes to show that their relationship was a success despite not ending up together.
