With something like Star Wars.. if the heroes won at the end of your last movie, tread carefully before resetting the game board so that in truth, they actually lost. Tread carefully on giving us new interpretations of old characters, especially ones that benefitted (and inspired people) for being simple archetypes.. I'm not saying you can't change them, but handle changes delicately.
That's the difference, I for one am enjoying the new game board and the new interpretations of old characters. Tragedy in their various lives (Luke, Leia, Han) sent them on separate paths.
I will agree there is a lot to explore there, but not in a two-hour movie, even a trilogy. The box office has become a center of spectacle, thanks in large part to A New Hope. It seems we've come full circle.
