I don't have any issues with large eyes styles. They are indeed very expressive. But they tend to get pushed to their most child like extremes on female characters who are supposed to be adults and when those eyes are combined with faces that taper to tiny chins the results get downright bug like. I like the way Elsa looks but I'd say they pushed those proportions to the most extreme I'd want to see them, and I'd be quite fine with the design pulled back a bit. Male faces may also have large eyes, but they also tend to have more..well, face to balance that out. Elsa's face, for example, would have its chin about where Aladdin's lower lip is. Male faces also tend to have other features that do a better job of expressing older ages. Female faces tend have tiny noses and tiny chins. All of these make them look younger, you can'd deny that. Finally, while large eyes are expressive, they don't need to be as large as they often get just for the sake of expressiveness. Plenty of much smaller eyed characters are just as expressive.
