Goldsman still sucks. If he manages to somehow defy the laws of physics and do a faithful adaptation of The Dark Tower, then maybe I'll forgive him for ruining the Batman franchise.
However, he's done plenty of crappy work SINCE Batman & Robin, and I think that's why there's still cause for concern: Lost in Space, Practical Magic, Deep Blue Sea, I Robot, The Da Vinci Code and I Am Legend. Now, he did write A Beautiful Mind and Cinderella Man... and Angels & Demons wasn't bad (a hell of a step-up from the hack job he did on Da Vinci Code). I haven't watched Fringe, so I can't comment on that. Still, it doesn't inspire a lot of confidence when you consider that The Dark Tower is one of the most epic and complicated stories ever written and it would be very easy to muck it up.
I'm glad this series is getting adapted... I just can't help but feel that there are people out there who would be much, much better for it.
