Elsa, who every little girl dresses up like for Halloween, is an odd character. Her parents were horrible to her, encouraging her to lock herself up after what was clearly an accident. And then she finally breaks free and runs away and ... locks herself up again. She doesn't really do anything (other than making that gorgeous ice palace). It's Anna who is the hero: she searches for Elsa, battles adverse conditions and makes the ultimate sacrifice to save her sister - but it's Elsa who all the little girls emulate and love. Anna (yes, annoying at times but she had a crappy, limited childhood) gets shafted, in my opinion.
