This iteration of Frollo is pretty by the book except for the lack of backstory and alchemy. He doesn’t have a brother but since the ballet doesn’t go in Frollo’s motivates for looking after Quasimodo there is a little point to Jehan as character. Not complaining, never liked Jehan.
This Frollo is a priest and hangs out with Quasimodo. This Frollo does all the classic thing you would expect from a fairy straightforward Book, like obsesses over Esmeralda but feel tortured over the lack of control and then gets pulled down into committing terrible action against her and Phoebus.
I’d say it was pretty standard although half the time Frollo is a creepy villain instead of creepy villain who was good yet stern guy who tried but couldn’t beat his own chemical impulses when he saw a really pretty girl. I’m trivializing Frollo’s internal struggles but even with the limitations of a ballet this version does get the point of Frollo across.
