Very true. Make that past stars focus - as a way to pull in the older demographic.
You're right. Luke "knows" he's fast.
It'll be interesting to see what he does, he has a reputation for starting a lot of things and letting other people finish them, Lost, cough cough - this time, he's finishing. I'm guessing he'll have a lot of help, maybe he can enlist Kasdan again.
I think I read episode 9 will be the final one for Rey, not sure about Kylo/Ben, but looks that way, the Rian Johnson trilogy will be all new.
