Man, this movie was great.
Now, obviously there's going to be salty AF people who was angry about their waifu not winning, but to be honest, even as a manga reader who once was for one of the losing girls, I was extremely satisfied by the ending, and how it ended all of the girls perfectly, with them all being given ample screen time. They really played around with the pacing, but in a way that made sense, and I actually felt like this is, by far, above the manga.
I thought the pacing for the movie would have felt rushed AF, since they went from 12 episodes covering 32 chapters in the first season, to 54 chapters in the second season, to 35 chapters in just the final movie, which, length wise, is the equivalent of less than 6 episodes. However, that wasn't the case. The series composer, the guy who basically makes sure the pacing and dialogue is solidified, managed to not just adapt every major moment of the series, it also managed to do it while adding more content that made the ending from an 8 out of 10 movie to a 9. The humor of it, despite me remembering reading it, also was made really well by the voice actors, bless them all, who delivered on the production incredibly well. The movie itself had meh production values, but that's sort of to be expected. Art direction was solid though, and same with composite, really made up for the stillness of the film overall.
Watching all of those events unfold, I forgot why so many people hated the ending, even if their girl didn't win. It was so satisfying to see the girl who did win finally get Futaro, and seeing the wedding, where this is spoilerless, and having to have Futaro guess between the girls just really made me laugh, even as someone who was decently sad about the girl I was rooting for losing.
Anyways, man, I'm sad that this is the end of the show, and series, but I'm glad it had such a fantastic, satisfying conclusion.
