I could imagine a Boba Fett movie in the style of, say, Lone Wolf And Cub or The Professional, have him be a more static character protecting and killing a client, navigating his way through the murkier parts of the Star Wars universe.  Have a finale where he fights those other bounty hunters from Empire Strikes Back, that kind of thing.  Instead of Cloud City, maybe an underwater city, they could flood it or something.  That could be neat.

And yeah, they might continue doing Episodes, but I think they need 3-Ep plans before they start, it just makes sense.  We read the Episodes as trilogies.  So I'm sure we could get a fourth one, but I imagine that, too, will start with a new cast in a new era.  But I'd like to see more of Finn and Rey outside of their episodes, I want this new world to continue some more, you know?
