This is probably a must-watch for Nagano Mei's fans, because she did brilliantly in this movie. She usually play that pretty, sweet, good-mannered type of character so I'm kinda surprised she could pull off Shiina's character well. I haven't read the manga but people said this movie is very close to the original manga. The story is good, the acting is great, supporting characters also did well....but one thing I should say (or warn, maybe), this movie could make you sleepy. If you're not a fan of slow paced, poetic lines kind of movie, you should probably know about this in advance.... I skipped some 'muted' scenes (no dialogue, just the actors or the scenery) because I was feeling drowsy watching it.

I understand though, maybe the cinematography in this movie was intended to be the exact same as the manga, as much as possible. But in my opinion they should have added some nice, sentimental music in the background maybe? To make it more...idk, dramatic? Because it's not a plain 2D pictures audience is watching, it's a movie adaptation so I guess some more music in the background would be nice! Especially for audiences who haven't read the manga and couldn't grasp the emotion delivered by the main character from the original piece like me.
I gave it 7.5 out of 10 because I personally do not like slow paced-type of movie. But other than that, it was pretty good.
