Story: 6/10
Honestly, the story bit is quite weak. After reading the synopsis, I expected to see a story about, as it states, "a pair of sisters". According to it, both "cursed sisters" are going to investigate an anomaly that suddenly appeared next to their house and being ported to our modern world. Yet, in reality, only one of the siblings is appearing in our world, while the second one stays behind and can only help the first one using a magical crystal ball.
Regardless, it is a good story, if you let yourself forget about the not-so-small discrepancies between the synopsis and the actual plot. It is a kind adventure story about a magic user trying to fix the problems that happened to our world. It explores the human's greed and selflessness and teaches to abandon the selfish wishes caring about others instead.
Being an overall kind and bright story, it has major plot holes that are hard to ignore. Such as, it is never explained why some building exist in both magic world and real world, while other ones just disappear from their original place. Moreover, the story is never expanded on what is happening to the people that were originally in those "disappeared" buildings and if they are even alive at the end of the story.
Art: 9/10
The art is without a doubt the strongest bit. Bright colours of the magical world stand out on the background of the real world creating a nice contrast. The animation is mostly flawless, and although there is nothing outstandingly great about it, it is quite unique and remarkable.
Sound: 8/10
The ending theme is great. Apart from that, there is nothing much to talk about sound wise. There are several moments when background music could help create a brighter picture but it just wasn't there. For the rest of the times, OSTs were picked well and matched the atmosphere of the movie.
Characters: 5/10
This is honestly the weakest bit of the movie. The only character who got a proper development is the main heorine, Yoyo. The second one would be probably the little girl named Aki. Yoyo's sister, Nene, although she is tagged as the "main" character, got less screening time than several of the supporting ones. I am probably biased, as Nene's seiyuu was one of the main reasons I originally decided to watch this movie, but I still think she could get more development being one of the two main characters.
Takahiro, who you could probably call a second main character according to the amount of screen time he got, still lacks a proper development. He acts harsh and rude sometimes, lacking any empathy for his parent (who turned into slime monsters, dammit!), being kind and supportive in other times, then suddenly he's switching on tsundere elements and goes blushing.
Most of the background characters, on the other note, are well implemented, and the guy from the ambulance team honestly made me smile.
Enjoyment: 9/10
Yes, regardless of those small flaws (and the fact that my video was buffering most of the times), this was still a good movie and I enjoyed it a lot. It was supposed to be a kind family-friendly magic story, and it definitely reached this goal.
Overall: 7/10
Majokko Shimai no Yoyo to Nene is not an outstandingly good movie, but it is definitely worth watching. It is a simple, yet an enlightening story that most people could probably enjoy. Ecpecially if you like magical girl stories, "Little Witch Academia" atmosphere and warm adventures, this movie won't leave you disappointed.
