Not watching the OT before writing the PT.
Lol, true, but I think his worst decision with the PT was not letting someone else direct it. He’s a big picture story guy, but he’s no good with actors or dialogue.
The fundamental problems with the PT lie within their scripts…they’re broken on essentially every level. Hand a blind squirrel a camera and as long as the scripts are solid you would end up with a better PT than what we got.
