I took the kids to Frozen and thought it was quite sweet. However, there seems to be a lot of adults that love it. You can't look at Facebook without some Frozen 'parody' being posted or someone saying "Let it go".
I understand why kids like it, but I don't really get adults going crazy for it. I know women that have watched it more than once, without kids!
I like it, not love it. I like the fact that the movie gives a message of "true love" apart from the one between a man and a woman, i.e. between the two sisters. I like the family message: to go out of your way for family. I like the character development, the graphics, the songs, love Olaf. There is nothing I don't like about the movie.
I like Frozen, but I don't love it. I don't know what has made this Disney movie so popular compared to others. For me there is too much singing, and the songs are too pop culture. I think the songs are actually what have made many people love it so much.
I love it and my 3.5 yr old son adores it too.
For me the appeal is that the songs have a very musical feel to it (similar to a Broadway musical), and the characters are feisty and likeable. I'm a fan of the heroine Anna having a bit of extra spirit in her, and also of Olaf and some of his humorous lines. If you're not a fan of musicals I think you could find it a bit too sing-song compared to other Disney movies.
