Well, I know this movie was set a long time 前 (Genie: "That outfit is sooo 3rd Century") but don't あなた think that Jasmine's at least a little bit young? At the start of the movie she is 15, 3 days from her 16th b'day. によって the end of the movie she's 16. But によって her confidence, looks and place in life I thought she was in her 20's!
So, I just think that によって stating ジャスミン as 15/16 they portrayed アラジン as pretty young too :/
Yeah, well thats just my opinion. I think they should've 発言しました "You need to marry a prince によって your 21st b'day" または something. :)
