I’ve thought for a long time they needed to reboot the show if it were going to continue – after 3A could have worked. It seems like I’m in the minority here, but as long as A & E give any exiting characters a satisfying “happy ending,” I wouldn’t mind seeing an aged up Henry and his sister beginning brand new adventures. OUAT’s basic concept of putting twists on classic stories has almost an endless pool to draw from, and I think the show could still be interesting with a male lead. They can also keep any cast on and keep them the same age with magic, curses, etc. – this show has never shied away from having characters look younger than they really are through not aging because X,Y,Z. All this said, I realize A & E would have to create a very compelling brand new plot line to keep people watching, and I don’t know if they can/will do that.
