Who writes the script is a moot point now that it's done. And yes, it was the LOTR team (Jackson, Walsh, and Boyens) along with Del Toro. Sorry petty.
I agree that PJ is a good director but I would haved like to see a less LOTR-style adaptation. However, at this point in the project, we're going to see that no matter who directs. I just hope that PJ directs more like he did with [i:379dxpy7]The Fellowship of the Ring[/i:379dxpy7] than he did with [i:379dxpy7]King Kong[/i:379dxpy7].
