These particular breeds of theory articles annoy me a great deal, mostly because A) the bad guys and the good guys in the fiction being discussed are usually are pretty clearly defined in the first place, B) the 'theorists' are motivated by more... carnal intentions more often than not (on the less severe end of this, they write them because they like the villain's tailor) and C) often they'll vilify the good guys to make their point.
Don't get me wrong, I actually do think that maybe the Jedi weren't all that pious in the end, but if I evaluate the individual actions of Obi-Wan, Yoda, Windu and others (especially after The Clone Wars) against the actions of Maul, Dooku, Sidious and Vader, I'm not really walking away wondering who I would want to invite over for dinner, if I had too.*
I can understand it when the fiction isn't so clear cut (black and gray, white and gray, gray and gray) (or if the original work's author is really dumb and uses protagonist-centered morality, but even with the sub-standard writing of the Prequels, I would say they at least are clear cut).
*The real question to ask yourself: what's for dinner?
Okay, rant over. Carry on.
