I don't want JJ to listen to Disney if they tell him to tone down the gore or make it more "kid friendly". Star Wars had an onscreen neck snapping, a bloody dismemberment, the smoking corpses of a married couple and the onscreen deaths of most of the members of a fighter squadron, as well as the destruction of an entire planet's population. It didn't need to be kid friendly, and neither does this.
I don't want JJ to include anything in the movie purely because previous episodes also contained said things. If the story can more naturally be told without a single lightsaber fight, so be it.
In fact, I don't want to see many references at all to previous episodes. To quote Steve Jobs: "A lot of times, people don't know what they want until you show it to them". If there is a choice between showing me something that I've seen before and something new, surprise me.
I DO want Star Wars to surprise me again. I want to be left not knowing what will happen next, and being interested in the outcome. I want JJ and Kasdan to have thought deeply about what the primary message of Star Wars really is, and if the saga is to end with episodes 7, 8, and 9, to make this final installment in the trilogy of trilogies be a revelation that deepens and redefines the previous trilogies as well.
A guy can dream.
