Oh yeah -- it was a whole thing too for awhile too on how fans decried Emma Watson growing up pretty meant movie!Hermione was made more attractive because they wanted to capitalized on Emma's looks --- so Hermione became more put together in the later films (sleeker hair that was pulled back from her face, the change to more casual clothing and not uniforms meant she was given 'cute' outfits).

In the same token - Bonnie Wright got criticized for not growing up as cute as everyone thought she should have been to play Ginny.
