I found a short click on YouTube regarding Merida's coronation in Disneyland.
For say, in Frozen, to cure Anna (protagonist), she need an act of love. Every character in the movie assume it is the "True Love Kiss". I was really angry during this scene. I thought "blah... boring true love kiss plot, which can never happen in real life. Meh... I can expect what will happen next~" . However, it turns out, it's her sister, Elsa (deuteragonist) the Queen saved her by hugging her and crying. I am not saying this is anywhere near to reality compare to "True Love Kiss" , but the moral value is very different. Instead of waiting for someone (typically a guy) to save them, love of sister (or family) is just as significant; instead of waiting for God to drop you a guy, family 's love is as magical as opposite sex's love. However, Disney still arrange a guy over to help these princesses. Perhaps they are worry that w/o the Prince, Disney movie will lost support from romantics fans? As for Frozen, the Prince has become the villain, which reflect real life situation, whereby not all love is true and loyal.
Compare to 40-50 years ago, viewers can never imagine this kind of plot twist. I wonder if they will be one day a Lesbian Princess? Just saying... something that usual now was impossible back then.
