The dream imagery and music, as well the development of Sailormoon's character and her relationship with Chibimoon, are the strong points of this film.
The final theatrical Sailor Moon film based off the original anime, the movie was produced during the run of Sailor Moon SuperS which adapted the Dream arc of the manga. The movie with its emphasis on dreams and Pied Piper of Hamlin by way of Hansel and Gretel narrative falls well in line with the established tone and aesthetic that characterized the arc run at the time. Fan reaction is pretty divided on SuperS because of its focus on the equally divisive Chibi-Usa, but I personally don't mind the arc. Admittedly the biggest drag on SuperS is the fact it's burdened with following in the steps of S that adapted arguably the strongest most "stakey" arc with the Death Busters, and following that very strong and often dark arc with an arc based around circus iconography and dreams was always going to pale in comparison. While Chibi-Usa was very grating in Sailor Moon R and her inclusion as Sailor Chibi-Moon in Sailor Moon S was often used as a running gag in how "stupid" the show seemed to think Sailor Chibi-Moon was as a concept. Sailor Moon SuperS for all you can criticize about it at least tried to build Chibi-Usa as a character which I personally felt was more successful than not (though your mileage may vary). Sailor Moon SuperS: The Movie on the other hand not only feels like an abridged version of many of the elements seen in the SuperS arc of the anime, but it's also lacking in an emotional core like Sailor Moon S: The Movie managed to establish, and feels like there's too much in too little time.
