I think they all should stay for the next three movies. They are growing up as the characters the casting people make it seem as if the hogwarts students are from neverland and don't age. Sorry news flash they get older just like the rest of us and the trio is growing up in about the same amount of time as they are in the movies (almost) it should be illegal to replace these kids. So what if they look a little bit older then their character I'm 22 and i look 16 I have a friend who is 46 and looks 28 no one looks their age these days anymore so what is the point. okay and where any of the people who played in Dawson's creek teenagers No they were all in their 20's also the same thing with Beverly Hills 90210 when it was on they can't change the characters they are too pivitol to the success of the movies when they leave most of the fans will too.



sorry for ranting just giving my 2 cents
