>>96536622I think you could actually get a little mileage out of that. The key though would be to not make the king the main character. If he is, then we'll be encountering his self-righteous harridans all the time. Which means the audience will get sick of them pretty quickly and the story will devolve into a constant series of 'Take That! To avoid that, you'd need to develop the family which could be done.
I could see the first arc working like this: princess kept in the castle (boo! restrictive king!) wants to be out doing stuff, hears about [EVENT] outside the keep and sneaks out with her little sister, their trusty female friends to resolve [EVENT]. They get into some hijinks, solve some issues on their own, but they unknowingly get deeper and deeper and the situation gets worse and worse. Meanwhile, we've been following the king, who is incredibly pissed off (boo! he's an angry guy mad at the wimmin!) as he tries to track them down.
Climax of the story, princesses and their associates have tried to slay the evil wizard/negotiate with the orc barbarians/defeat the cultists/whatever, but they've gotten far, far over their heads and it looks like curtains!
Suddenly, knights and the king appear! Huge dramatic battle and all that. King is righteously pissed - he's had to take his knights to track down his daughters, he's lost soldiers fighting this whatever, etc.
Oldest daughter tells him he's so repressive, she needs to be free. He sees that she is capable (despite nearly getting eaten/killed) but he explains that she wasn't his only child. All her siblings died in childhood - disease or injury and after his wife died bearing her, he became overprotective. She's not only his only heir, but his only surviving child and the only thing he has of his beloved wife. So they both learn a little. He, that he doesn't need to be so restrictive and that his daughter(s) can take care of themselves somewhat, they that their father isn't some ogre trying to oppress them.
