I just saw Episode 3 again, and found that the second time around the bad points stick out even more. As a character, Anakin is a lost cause. Vader, on the other hand, is still the most badass villian ever. Seeing the original trilogy again today proved it. Vader being rebuilt, putting the mask on, breathing, and being lifted from the table are all great. Unfortunately, what follows ruins a great scene. Having any out of character moments in those few minutes of screentime is a disgrace on Lucas' part. My solution to this is that after the Emperor asks Vader the question, he responds with a "Yes, master" taken from the original trilogy, and quickly cut away right there. This preserves Vader's mystique and individuality.
