I'm going to watch it this weekend. So far, the acting and the attention to detail have gotten a lot of praise. I have zero faith in Amazon but I'm hopeful the other parties involved had enough input to steer it in a good direction.
Since the other thread was closed, I'm just going to repeat what I said there:
Tim Cain, the creator of the first Fallout, was invited to the premiere (first two episodes) in Hollywood and said he loved it. I look forward to the "I hate Bethesda Fallout" crowd being extra salty about that.
He also took a picture with Tod Howard and asked fans of the first game to stop being so obnoxious online.
