I always found issue with how the movies aged up Snape, Lily and the Marauders, making their deaths seam less tragic in a way, they were only 21 they had only been out of school for 4 years when they died, and the movies make them look like they were in their 30's which is realy disappointing, but one time they did this that realy annoyed me was with Ariana's portrait,

Yes she looks young-ish but Ariana was supposed to be 14! 14 years old when she died! and this picture she looks, 18, maybe 20, and yep, the actress who played her was 18 years old when they filmed it. I just wish they would have gone with a younger actress because it would have been so easy, the roll doesn't even require an speaking lines, just a little disappointed
