I think one can make the argument that many such films are more protodemocratic (not pro- but proto-; not actually for democracy, but philosophically headed in that direction). Specifically, the ones where the royal in question is fighting to save the peasants from the evil witch/bandits/Evil Duke/etc, and is acclaimed as a hero by the commoners for his or her efforts; they are treating the common people and their desires as if they matter, and the support of the common people as something of value. As opposed to just neglecting the needs and desires of the commoners, squeezing them for taxes, sending them off to die in wars, and stomping on them with the iron boot when they get out of line.
The more a king or queen tries to do what the people want and act in their interest, the more they are engaging is something close to an informal democracy. Although a clumsy, limited and unstable one since it lacks formal broad based polling (aka voting) of what people want, and lasts only as long as the royal feels like keeping it up.
