To be honest when I found out that there was a live action movie to kiss him, not me I was so excited. I watched the anime a few years ago and I remember just loving everything about it. I went into the movie sort of already knowing the whole plot but really excited to see what differences or changes they may have made.
However, I did NOT expect to see serinuma break out into song and dance ???? Literally wtf. That was not at all what I expected. The singing and songs were super cringy and I get that she was trying to narrate what she felt but it just wasn't working for me.

I also felt that the acting was really cringe and fake. Especially from the boys, their acting was super stiff and it was just extremely uncomfortable to watch tbh. I think maybe the cuteness and 'kawaii' serves better in anime than in a live action? And also maybe I wouldn't have been as tough of a critic if I had watched this when I watched the anime at the age of like 13.

Overall, the acting was just super cringe and uncomfortable. The breaking out into song also was not a plus and made the whole movie really awkward to watch. I really wish that they had adapted it into a more normal high school romance type live action but I get that serinuma was already quite eccentric in the anime so they just tried to duplicate that energy. I think that it just didn't work this time, especially because it wasn't an anime anymore, it was a live action.
