I’m struggling to find the right words about this one, truthfully. I will say that my fondness for it stems from childhood; giving it a perfect score is based on how much I enjoyed it when I first experienced it as a kid. However, there are established conventions within its genre, and it incorporates some—like the “water shortage” trope and the “roller skate” trope—but leaves out many others. Because of this, I don’t feel like it really fits comfortably within the genre it aims to be part of. Still, it was designed to appeal to both children and teenagers, and it certainly succeeded in that regard. The magical glowing ball from outer space, with its upbeat and positive atmosphere, definitely evokes a Disney vibe... specifically, 1980s Disney. It’s also full of political messaging—though I mean the kind associated with the 1980s, meaning it's not obvious or aggressive; it doesn't overwhelm the film. Because of that, unlike many contemporary movies, viewers can watch and understand the underlying messages without feeling like they are being lectured. That was a time when liberal politics focused on concepts like love and peace rather than violence and hatred, so it might feel out of step with today’s audiences who prefer more overt propaganda. It's almost certainly going to disappoint those expecting a standard genre film, because again, it doesn't embrace the familiar tropes and tries to tell a more unique story within that framework. Despite this, it holds up. Revisiting it in 2020, after first seeing it at age six, reveals that while it has aged, it hasn’t completely fallen apart. It didn't improve with age like a fine wine either; it simply matured gracefully and remains enjoyable and entertaining. It just doesn't feel as overwhelmingly wonderful as it did when I was younger and initially fell in love with the film. It still warrants recognition, even if its intended audience is getting older and looking for something more—or at least more reliant on genre clichés. If you decide to watch it, it’s worth your time... but experiencing it back in 1986 would have been truly fantastic.
