Here's a summary of reviews of Secret Society of the Second Born Royals:

New York Times: A strange mix of infant seduction (weaponized butterflies, lots of princesses) and adult politics (anti-monarchist protests, bomb threats at the coronation) The mixture of 'Second Born Royals' doesn't know how to make it kid-friendly without making fun of it."

Common Sense Media "A great idea for a Disney franchise or series, but as a stand-alone film it falls a bit flat. While the narrator does say that this is not a typical "princess story," the film follows the formula of a rebellious teen transformed into a superhero with powers and princess status (and ball gown)."
