I read the graphic novel a while ago; it was nice, but IMO it didn't transcend the target young demographic at which it's primarily aimed. I remember liking that they gave the prince a character flaw or two, so that he wasn't just two-dimensionally sympathetic; but the rest of it didn't stay with me. Judging by 'Frozen', I'm guessing that an adaptation by this creative team will similarly work for kids but not so much for adults (or, not for this adult). But I'm fine with there being more musicals that other demographics can enjoy, so hey, bring it on.
