See, my point is that I don't think the PT provides enough context to conclude that. I would suggest that you're basing that reading of the PT on more than just the films themselves. I don't think our understanding of the Jedi Order is deepened by the PT and I don't think it provides anything against which to judge that the Jedi got it wrong. The fact that you are defeated doesn't always mean that you acted wrongly.

Deepening our understanding of the Jedi Order, and the Sith Order come to that, in ways such as JamesEightBitStar is suggesting, would have given us more with which to compare the actual decisions and actions of the characters. I'm not talking about having my hand held, as you so generously suggested. I'm talking about an expression of the antiquity of the Jedi and Sith Orders and the beliefs and traditions they represent. The short scene in Ben's hut on Tatooine expresses more about the Jedi order than the whole PT, in my opinion.
