The more I think about it, the more I come down on the side of two choices:
Option 1: Make a full-bore epic trilogy to lay the foundation of what I've decided I will call Star Wars: The Next Generation (SW:TNG). That gives you 3 movies to lay everything out and build from, wiping the prequels and the ill will towards them off the map. If you do this -- Peter Jackson.
Option 2: Jump right into the Bond-style movie every couple of years plan. Brad Bird or Gore Verbinski could easily pull off a movie that could be very good without trying to do "everything" in 120 mins.
Chatting with Brian, he also tossed out another name (for option 2) that could be interesting...Darren Aronofsky. He was inches away from directing a Wolverine movie, so it's not like he's unwilling (or unable) to stray from the art house. He clearly has the talent for characters and an eye for visuals. I'd put him right behind Bird & Verbinski, if only because they both have more established records for what I think Disney will be looking for.
All told, I'm not coming down on either side (terrible or great) because we won't have anything to even base positivity/negativity on for several months. Admittedly, it's tough to imagine it getting "worse" than the prequels, but how many times have we been burned by that thought before?
For now, my state is "Cautiously Hopeful".
