Both candidates have directed a lot of television. Coincidently, they've both directed episodes of the critically acclaimed "Games of Thrones" on HBO. Taylor has quite a bit more experience. I'm pretty happy with this selection. Taylor's resume is impressive, and extensive.
I don't mean to take away from Taylor's qualifications, but really, the movie is going to make a lot of money regardless of who directs. That doesn't mean we should be ok with anything Taylor shoots, it's simply stating a fact. Even the WORST of superhero movies (Green Lantern) make money. Let's hope Taylor lives up to the quality of film Branagh has given us.
