Story : Spoilers ahead
Pretty good pace to be frank, the 2 hours flew-by. The only moments I felt were dragging were established character's moments, that's all (if you follow one piece this one wouldn't even be a problem). The story was a story, I can't really develop this point onwards. Just a nitpick was Uta throwing away the medicine, that she have used after her final song
Art :
Gorgeous, really the musical numbers were some of the prettiest I've ever seen. The animation was really amazing for real. I just had one problem and it was the storyboard for some action scenes that was really messy, making the action scenes hard to follow. But thank god this problem doesn't apply to the final fight scene that was beatifully done. Also love how Uta moves around, such personality in small details
Sound :
Surprised by some performances and overall the cast did a good job, especially uta. The songs were wonderful, changing as the story goes along. They were also sung by a different person, Ado, that has an amazing voice. I was stunned by her vocal perfomances
Characters :
That's where I reduced some points because I had little to no idea who they were. Most of them were put there for fanservice for sure. I can only speak about characters that were developped Uta and her teacher. I would say Uta is a good character and her teacher is someone I didn't like as much
Enjoyement :
I'm an idol and jpop fan so the songs instantly appealed to me, same goes for the wonderful animation and nice cast, so I can say I had a pretty good time
Overall :
It was really a nice movie for both fans and non-fans. It's really worth it, seriously consider giving it a watch
