This question may have been better asked at a general Disney forum rather than one that deals with The Lion King.
I voted for TLK. Because it`s amazing and in my mind nothing will ever top it.
Do I like Frozen? No. I LOVE IT!! I can easily add it to my list of top 10 Disney films.
I saw the Norwegian dubbed version at the cinema and about a week later they showed the English version. I really enjoyed Frozen from the start, I loved how the focus was on the sibling relationship rather than falling in love... (this was of course also an important part, but dealt with in a refreshing way) I thought the animation was breathtaking, and the music was wonderful. Certainly different than the beautiful orchestra pieces we`re used to from more classic films, and with the excpetion of "In Summer" I think Frozen has a great soundtrack.
On top of this, the setting of the film is based on Norway, my home country!! The excitement I felt when sitting in the theatre watching it for the first time is hard to describe. There are so many references to Norwegian/Scandinavian history, language, architecture, culture and nature that I couldn`t help not falling in love with this film.
I felt the characters are complex and engaging, I could relate to both Elsa and Anna in different ways, and I absolutely adore Olaf. He`s one of the very few comic relief characters that are never annoying or selfish, he`s just sweet, kind and really funny.
I know many people think it`s overrated and many people don`t like it, this is how it will always be, we`re all different, and that`s good!
To compare Frozen with other recent Disney films, I prefer it over Tangled, Wreck-It-Ralph, Princess and the Frog (Love, love Tiana though!) and Bolt.. I really, really enjoyed Toy Story 3 and Brave as well, but I prefer Frozen over these two also, if just slightly.
