Statistically speaking, I am almost certain (I haven't checked shit) that merchandise for this series has sold exponentially higher than anything we have ever seen for the romance genre. The Quintuplets fanbase isn't huge on Anilist or Myanimelist but rest assured, this series has a massive following. On top of that, its fans take it seriously, true die-hard supporters who love the series with all their heart. I would like to think I'm not as delusional but this is one of my favorite series of all time, period. I understand the ending rubbed a lot of people the wrong way and made them ultimately dislike the series, due to the ending. I can understand why, even if I don't necessarily understand. BUT, look back on the series. If you truly enjoyed it enough to sit through both series and get to the movie and ending, it's time you gave the series a second chance (unless you loved it of course).
When I say this, I'm not saying you should like the series even if you didn't like the ending, nor am I trying to convince you to reconsider your opinion of the series. The whole reason I say the series deserves a second chance is because I feel that so many people turned their back on the series that it left the animators stuck between a rock and a hard place. (SPOILER WARNING, but I mean, surely you have seen/read the series if you are considering watching this) People who were mad that Yotusba won complained that she didn't have any screentime, wasn't foreshadowed well and didn't get enough development with her relationship with Futaro period. On the other hand, the Miku and Nino fans would have ultimately dropped the series prematurely if it became evident that Yotsuba was gonna win, which would have been inevitable if she randomly started getting a lot of panels in the manga, and screentime in the anime. I'm not blaming Yotsuba haters or Miku or Nino fans here, nor am I blaming the studio. It's just the way it goes in a harem. Unless you go for the polyamorous route (which nobody would have liked), something has to be sacrificed. For that reason, I don't think the series should be written off ENTIRELY because of something that is simply an inherent flaw of the genre. Imagine the scenes if Miku or Nino won, the opposite fanbase would go even more ballistic. I want to reiterate, i'm not trying to argue against or convince people who didn't like the series because of the ending. The ending matters. I agree. However, I think that people have greatly overreacted to the ending, it certainly isn't one of the worst ones of all time.
Shaft goes for fanservice here, big surprise. I mean the series already ended but they are animating extra chapters, of course it's a cash grab. But the animation is top-notch, on par with Monogatari one could say. As I mentioned previously, the animators are stuck in a tough situation where they have to provide development for the seemingly random and arbitrary Yotsuba victory while satiating the desire of Miku and Nino viewers to come back to watch this special despite losing out to Yotsuba. This movie/special does just that, it gives Miku and Nino their screentime with Futaro to start, showcasing their cute and loveable characters, then seamlessly transitioning into the heartfelt Yotsuba segment, and how they met years ago as well as her feelings for Futaro which she locked away in favor of giving her sisters a chance, just like how they gave her a chance after her academic failure at her previous school. When it's all said and done, this movie/special can make everyone happy. All it needs is a chance. If you have seen/read Quintuplets, watch this. It's only 50 or so minutes and provides everyone with entertainment, even if the series may have left a bad taste in your mouth. I didn't like some of the fanservice, I felt like those were the wrong chapters to animate and made the characters not themselves in a way. It's still one of my favorite series' tho and this special gets the job done for everybody I am ultimately quite pleased even if they simply reopened the series just to make a few extra dollars. Final Score: 8/10; thank you for reading!
