"James Cameron Won't Direct..." is enough to put a smile on my face most days. So, thanks.
About directors of the future: Nolan is my top on that list. Quentin is another definite. I'd like to absolutely add Darren Aronofsky to that list as well. Also David Fincher. Along with Zack Snyder, Wes Anderson, Paul Thomas Anderson and Jason Reitman to name a few.
And I agree with genesis. Spielberg isn't as good as he used to be. I don't agree that the two movies in question were as bad as genesis claims (weren't his greatest work though), and definitely don't think Avatar was any better than either really. But Spielberg has lost a step since his prime. But he can still put out some fun movies.
