While I agree with the the overall article, I think it's important for parents to talk to there kids about anything they watch/read/consume.
There is nothing wrong with men wanting to be the knights in shining armor or the women wanting to feel like a princess. It's nice to have dreams like this as long as you don't get lost in them.
Wanting to be a princess is fine if it doesn't come with additional things which states that only a prince can make their life better and they can't do it by themselves !!
