Cast/Acting:
I think they picked the right cast. Honda tsubasa really fits the role of Futaba in my opinion.
In the manga Kou was fighting for Futabas love more than they did in the live action, but I think the actor did still play a good role.


Story:
I have collected and read all thr manga and I think the live action does follow it most of the time, but some scenes they took from the manga and changed a bit, so that it would all make sense.
Considering they (only) had about 2hrs of screentime I think the story prgressed well...


Music:
For me the Anime/Movie OST is one of the most important things about a movie and I think the ost was pretty good


Overall:
I think the live action is good, cause it has more of the manga in it. The anime sadly only consists of the 1st 3 volumes of the manga. I collected all the volumes and know that the whole plot comes in kinda later on. I think it's a great story, but the anime itself is dry. I really like the live action though.
