If you really love UtaPri--music, characters, and all--then you'll love this movie because it's basically just an animated concert between STARISH, HEAVENS, and QUARTET NIGHT with some chit-chatting in between. Music-wise, I'm not the biggest fan of the UtaPri music except in some places, so I wasn't 100% impressed with the music in this film. However, like I said, you'll probably like it if the UtaPri sound is your thing. The art is usually gorgeous in UtaPri, and the dance choreography was amazing the entire time, but the use of CGI for the dancing wasn't that nice to watch. Obviously, there's no story to discuss, but thebanter between the boys was funny enough. I do tend to think that you need to expect a certain amount of cringe when it comes to UtaPri, and that was definitely present in this film, but since UtaPri is a guilt pleasure of mine, it didn't bother me too much.
So, yeah. Not much to say. Watch this if you love UtaPri because it's a really cool experience to kind of see them in concert.
