I still don't see why some people found it weird that the actors grew up - they grow up in the books, after all, and the changes seemed to map out to that OK. To my eyes they look like 11-year-olds in movie 1, 14-year-olds in movie 4, 16-year-olds in movie 6, etc., just like they're supposed to.

(would have been far weirder if they didn't!)
