Wow, losing the “what have I done?” REALLY helps that scene in RotS.
You really think so ? Because only 5 minutes later Anakin has no second thoughts killing Jedi (and kids !) in the Temple.
Well yeah, that’s the whole problem with it. If he’s gonna suddenly be bad (which is another failure, btw), he should not be regretting it in advance just five minutes prior! Not to mention the fact that he says the line, and then two seconds later pledges his allegiance to the dark side. So, yeah, what have you done? Said a line that was a complete throwaway. It was nothing more than Lucas trying to show a complex character and having no clue how to do it. That’s not how you show internal conflict, George.
The PT took one of the greatest movie villains ever and made him a whiny baby. “What have I done?” my ass. OT Vader doesn’t ask stupid questions like that.
