Like Khalin, I tended to like the villains more. I still do. Few seem interesting enough to have a movie about them because they aren't explored in the original film.

But on the other hand, I sort of like them merely being evil. Do I really want to find out Scar's dad raped him and told him he would amount to nothing every day? That wouldn't justify his actions, but it should shed new light on them and reduce the impact of the happy ending because he's more sympathetic now. (Obviously they wouldn't do something that extreme. I'm going for a point here.)
