What makes me upset about that was that Rinoa actually had to be the potential to be a realistic, intriguing FF heroine until Square made her a Sue.

When you first meet her, she's a spoiled rich girl playing war. She has no idea what to do, and really seems to only be doing it to rebel against her father. She's surprised at Squall's harshness and how much more experienced and calm the rest of the party is.

...then she gets her Sorceress powers and everything goes down the drain.
