For me this was a tale of two parts. First half of the movie I was genuinely amused. I was giggling really often mostly because I was constantly like omg these boys are being so stupid that it's frickin' hilarious like the whole thing with the bathroom, or the dramatics of just handing over a roll of tape. (I wouldn't count these as spoilers). But then I hit the 2nd half of the movie and it started to drag. I noticed myself getting fidgety, going on my phone. I guess the school festival parts were too long and tempted me to do some skipping. As for the cast, although nobody really stood out, they were all reasonably believable to me as a bunch of high school boys and girls. The only memorable one for me was Yoshitake, but that's because he's the only actor I recognized from elsewhere. At some point during the movie I realized he played Taichi in Chihayafuru live action except with very different hair. Didn't take note of any music so I guess it must've been either sufficient without standing out or it was a movie without much music. I would not rewatch the movie again, but wouldn't mind rewatching clips of some scenes.
