The Grim's version were far darker than disney's. Anyway, it is not heterosexual relationships that people critizices, it is the "damsel in distress".

Snow white and sleeping beauty are an example. They don't fall in love with the prince before the kiss, but after. They don't even know the prince before they fall sleep/get poisoned/cursed.

Sleeping beauty is not waiting for the prince, but for someone, anyone, to wake her up. Assume that just because he wake her up she should love him, is where lies the problem. Same with snow white. And in both cases, the only thing that the prince knows about the princess is that she is beautiful. No previous interaction between the two.

Cinderella is slightly better in the sense that she at least know the prince a little. But the prince only knows that she is beautiful and she only knows that he is handsome and a prince. All her hard work is not considered by the prince. If she was ugly, she would still be abused by the step mother and stepsisters...

As for the beauty and the beast, the problem is that the beast is abusive to Belle. So while we are expected to take a look of inner beauty, what we are really seen is that a woman should turn a "beast" into a man. Make him become better.

I do agree with Mulan. It shows it is a latter film, with more modern values.

The little mermaid is alos troublesome because she gives up her voice for a man she doesn't even know. The original version is sadder, but better. She doesn't give up her voice to explore, she does for a man.

I'm sure that people can still enjoy those films and it is ok for children to still see them. But being critic with them is also OK. You can do both.

And I'm sure we would see an evolution of children films to reflect current values. I do find interesting to look at those films with the perspective of time. The thing is that feminist interpretation might not be missing the "morals" of the story, but giving additional layers to that.
