He was perfection. And that is why-- although I wanted the big Skywalker stuff saved for the main series-- I now desperately want something like Jedi Academy: A Star Wars Story or Master and Apprentice: A Star Wars Story. Something like that.
It'd be Luke, as he appears in the projection (but with the right 'saber), dealing with being a Jedi Master and his Naughty Nephew-- who'd be a teen, and thus not have to be played by Driver pretending to be younger.
Have them on a big mission outside of the Republic's territory. Ben, still pissy at his parents for shipping him off to his uncle, finding out about the Vader lineage and most importantly the Chosen One prophecy (and it all goes to his head, he's more interested in it-- in kind of a vain way-- than Luke would like), Luke admitting that all Skywalkers have struggled with the Dark Side but ultimately come out on top. Luke wary of the future.
Come on. Gives us something, LFL.
