I think after the prequels, the Jedi thing just stopped being as cool. George pretty much jumped that shark with a rocket boosted set of skis.
I think anything set in the Star Wars universe could be entertaining if done right. Bounty hunters, smugglers, pilots, soldiers, mercs, cantina bartenders, and so on and so forth could make for a hell of an interesting film. Hell, you could do a real gritty film about civilian life during the Imperial takeover and it would be just as interesting.
