Sailor Moon in general is and always has been about the power of love and friendship, which is adorable. In this movie, there is a certain undertone of homo attraction from Fiore towards Mamoru: Usagi's boyfriend. As the story goes, it's understood why everything is happening just the way that it is, although you might get a little confused at the very beginning. The animation is smooth, the art-style is beautiful, the characters are mostly very distinct from each other and the Sailor team completes each other's strengths an weaknesses well. I recommend this and think you'd definetely enjoy it if you're into shoujo.
