I think Disney shouldn’t adapt Expanded Universe storylines because it’s just lazy. I think I’d rather see Lawrence Kasdan’s take on Han Solo’s past than an adaptation of an obscure EU novel. I know there’s some good stuff in there, but why would you want to see the same story again?
Speaking for myself, I wouldn’t mind having parts of the old EU recanonized. Adapting some of the stories to the big screen would be a good way of getting this done.
