This "short film" spends the first five minutes giving us a behind-the-scenes, making-of featurette, which completely ruins what *should* have been a beautiful, immersive, 'Fantasia' style experience. Have the documentary thing *separate*, for goodness sake! I liked the documentary, but it didn't belong here, *before the film*... Anyway, the film itself is quite beautiful, with lovely narration and soundtrack. Apparently it serves as a prequel of-sorts to the Frozen 2 film, interestingly. I watched the 2D version on Disney+ but there is a superior, interactive version for virtual reality also available (probably without the documentary, too). Without the documentary bit at the beginning, this would make for lovely pre-bedtime viewing, as a "bedtime story" of sorts, but alas... Like I said in my title, it's wasted potential...
