After the All Stars DX trilogy, the writers decided to reinvent the plot structure for this crossover film: previously, the heroines would meet in one place, an antagonist would appear and they would all defeat him together. This time, the story begins with the defeat of the enemy, who will split into smaller pieces, scattered throughout the city. This fight can be seen in the opening, is not very long, is well animated and involves all the Precures. One strange thing, however, is that the monster faced is Fusion, who was already defeated in one of the old films and it is not explained how he returned. However, he will at least make use of the abilities he had previously demonstrated.

At this point, the focus shifts to the real protagonist of the story, named Ayumi, a shy girl who has just moved to a new town and struggles to make friends, until she meets a small creature called Fuu-chan. This, in reality, is a fragment of Fusion, which will gradually develop a consciousness of its own. I liked the concept whereby a piece of a purely evil being naturally becomes attached to a lonely girl and decides to protect her by using the only method he knows, even if it’s wrong: that of absorbing and eliminating various enemies. The scenes in which he does this with the neighbour's dog and his mother are also quite disturbing. That said, very nice reference to Wii Sport Tennis.

I had already heard of Cure Echo, but I was not at all prepared to see her in this film: her transformation gassed me a lot, she also has a nice design and a meaning behind her name. I appreciated her friendship with Fuu-chan and the message behind her character, namely that you have to communicate with others to make them understand your intentions.

Speaking of the various Precures, the Suite and Smile teams played important roles. I was pleased to note how the former were portrayed as much more experienced and capable, so they were admired. At the end, all the girls in these two groups had lines of dialogue and moments. In particular, I laughed at the scene in which Hibiki and Miyuki chase Ayumi and the former's speed is emphasised or in which Peace explains to Ayumi that they are very similar in everyday life. Nice to see Happy fighting alone together with the Suites.

More in the background, there are the Fresh and Heartcatch teams. A nice interaction between Peach and Marine has to be noted, which smacks of compensation for Erika OOC in DX2. The other Precures, from Futari wa to Yes 5, only appear to fight and will have no lines, which is a choice that makes sense: you can't have 29 protagonists and it's better to focus on just a few.

Despite the heavy reuse of animation, the fights are good, though not peak Precure. As for the soundtrack, I enjoyed the opening. Seeing Suite's henshin a few weeks later makes me further realise how much I liked them.
