I have never personally understood the appeal of Trolls. The whole franchise. I get ponies, I get Cabbage Patch Kids, and other ugly-to-me-but-really-popular-for-some-reason 80s phenomena. But I just don't get Trolls dolls, I don't see how anyone can genuinely find them cute (this movie helps in that regard a little, but the rock trolls from Frozen were cuter and no on cares about them), and I'm not sure what about their lore is interesting. Maybe you just had to be there. They just seems to endure despite all odds. Good on them, I guess.
Anyway, animated movies that feel the need to cram in sugary, kid-friendly pop songs every so often make me physically ill so they lost me on that point.
