I found it incredibly lackuster, with a boring, mostly predictable plot (the ending had a great twist, though) and only one memorable song (guess which). Character design was probbaly the worst I've even seen from Disney, with completely uninspired looks for everyone. It's SPECIALLY bad for Elsa and Anna, who look like the lost twins of Rapunzel. Elsa's Ice Queen outfit was the only good design, imo. The backgrounds were likewise very "meh", nothing particularly interesting or eye-catching (other than Elsa's Ice Castle, which, like everything about Elsa, was gorgeous).
The only things that I feel that give this movie redeeming factors is the ending twists (
), Olaf (that snowman really grew on me) and Elsa. DAMN that queen is awesome. Her ice powers are incredible, and I generally like characters of the "dignified fa?ade/terrified of themselves inside" kind. Anna is fine, but she's basically Rapunzel with shorter hair. They both have basically the same personality, quirks and mannerisms (bumbling spunky princess who talks very fast).
Overall, I'd say it was pretty damn weak, with some good moments that really don't hold the movie up as a whole. Eh well, another one to the pile of "great traditional stories that Disney diluted as much as possible".
...did I mention I really liked Elsa? I really liked Elsa. Best Disney Queen.
