Other reviews have already covered how great the cinematography is in All about Lily Chou Chou and how the music ties the story together so I won't go into depth about that. I just thought the movie was a masterpiece. I had never seen a film like this that had flawlessly interwoven all the things that makes life so beautiful and yet ugly. And the timeline wasn't confusing at all like I've seen people say. The years were told on screen and I knew the story went into the past around the middle of the movie because Hoshino had changed so much. Also, there were hints early on that Hasumi (philia) was talking to Hoshino (bluecat) online. We the audience knew that Hoshino was a Lily Chou-chou fan first and was the one that introduced Hasumi to the artist. Hoshino in the flashback scene had a Lily Chou-chou poster in his room and Hasumi asked who it was when he stayed over. It was interesting that in the present day timeline the person that caused Hasumi the most pain and was destroying his life in the real world was also the one that was giving him comfort online. It really goes to show that you don't know who you're speaking to in this internet universe. And the scene towards the end of the movie where the two worlds (cyber and real) collide at the Lily Chou-chou concert left a deep impression on me.
