Should children, or teens, or adults be exposed to fantasy good vs. bad (unfortunately for young ones - a snowman) where good triumphs & evil bad is vanquished in some way? Well, it's been that way forever (at least since humans started telling tales in caves). So no surprise there. My low rating is due to the animation & voicing. Animation wasn't the worst nor was it amongst the best. Had some 3-D, but in mostly a single moving character with layered painted looking backdrops that were static (not moving). And both, central characters & background, lacked detail. Voicing was too human like. Characters were too stereotypical cute - dragon looked like a green puppy; princess looked like most female animé: thin, attractive, big eyes, long light hair, white, and very "Frozen" like.
German & Chinese animators should catch up w/their neighbors.
