Substituting "whiny and weak" for "loves power for its own sake" just doesn't cut it.
Until you have to explain why someone who loves power for its own sake would be a Jedi in good standing in the first place.
That's not who he is, and we all know it.
There it is again. Apparently, the people who
don't know it don't actually exist. A 1996 source described Anakin as "weak", "foolish", "idealistic", "frail", and "blemished". The use of "is" in this context seems to imply that the character should be in stasis for his entire life. How is zero character development to be considered an improvement?
That would be okay if Palps were the main character and we were invited to root for him, despite his being evil and all.
Still an imaginary rule, invented just for this situation. It fails miserably when applied to the preexisting history of literature and film. And, no, you're not supposed to root for the villain, though that continues to be an amusing red herring.

( We hope. )
Maybe being a good little liberal, he's creeped out by/can't comprehend the part of human nature that likes being evil, enjoys it, and fantasizes about no longer having any restrictions on the unrestrained use of power.
Easily disproved by Palpatine and OT Vader. Perhaps he simply doesn't agree with you that Anakin should have represented that character type before turning to the dark side ( thus denigrating the importance of the turn as emphasized by the OT ). Maybe Lucas didn't actually participate in the Force retcon to which his name was clumsily and erroneously attached after the fact.
But the only reason the PT exists was to tell the backstory of Vader. The backstory of the Emperor isn't worth going to all that trouble for.
But the backstory of Vader, as far as we know from the OT, didn't feature Vader becoming omniscient, in charge of everything that happened, or exempt from manipulation by any other character. In fact, quite the contrary:
Luke, do not underestimate the powers of the Emperor, or suffer your father's fate you will. Once again Lucas is being damned simply for being consistent with his earlier films.
There was some sci fi novelist who wrote a rant once about how Star Wars is fascist. Damn right, it's fascist! It's terrible!!!
You might not be getting the intended message.
