Yes, I guess it makes some sense psychologically that a whiny little bitch could turn into Darth Vader but it didn’t make for a very compelling story. A shame Lucas starting getting high off his own farts.
The most interesting part of the second trilogy was the short story that Palpatine told Anakin about Darth Plagueis.

As with most of SW films, Ian McDiarmid was the best thing in the entire franchise. Not that some of the others were bad (the English thespians were all great: Christopher Lee, Alec Guinness, Peter Cushing). But McDiarmid played Palpatine with such relish it was a delight to see his scenes above the rest.
