However, what DID hit me tonight is just how out of the blue a major plot thread of the film is: Luke believing there’s still good in Vader. There’s absolutely zero reason for the viewer to think that, let alone Luke after the hell Vader causesd in ESB, but then when talking with Obi-Wan on Dagobah, Luke suddenly says he thinks Vader still has good in him and can be saved. Where the heck did that come from?!
This is why I can no longer buy into the Vader redemption arc. Two whole movies we’ve spent with the man beforehand, and the only time he ever exhibited anything resembling a redeeming trait was when he kept Fett from shooting Chewie, and that was probably done for ulterior reasons.
Show, don’t tell. A technique ROTJ failed badly to utilize.
