Obviously, I’ll wait and see once it comes out. But it seems odd to spend so much and not have a single established creator that has put out great content. And not to involve Jackson seems off because even having him in a consulting role would be a good sign. Looking at the imdb page this seems like a corporate driven project rather than a creator driven project with lots of different directors that haven’t don’t any…
As a huge ASOIAF fan, I had the same concerns after Game of Thrones was announced and first details were shared. The crucial difference, though, is that GRRM himself was involved in the series.
No one involved in this project appears to have the same level of involvement. Instead of someone like David Benioff bringing a property to the network to adapt and develop, Amazon spent out the ass in a bidding war over the rights and then hired people to run the show.
That can obviously work just fine, but in general, it works better when the showrunners and producers are the ones that pursued the material and sold it to the network (or steamer, in this case).
