I was 8 yrs old when I first saw SW EP4. I loved it. Most of us did. I think most of us were kids when we first saw SW EP4.
We cannot love a movie if we cannot care about the characters or even hate the characters.
I think the best movies are the ones in which the audience loves the protagonist, but at the same time feel sorry for the antagonist.
I learned in grade school that all stories need character developement and plot, among other things like setting, climax, and resolution.
I guess Lucas never learned that. Did he even go to school?
