Saw it. Not too bad. Better than the previous two, certainly. It still had some problems. Oddly enough, where I and II felt thin on story and thick with "filler", this one felt rushed in some crucial places. Like, f'rinstance, Anakin's turn to the dark side, where literally one line is "What have I done", and his next line is, "I will do whatever you ask," pledging his loyalty to the soon-to-be emperor.
Toward the end, I started to feel like we were going through a checklist of Things That Have to Happen to Set Up Episodes IV-VI: Luke & Leia born, check. Kids split between the Lars and Organa families, check. C-3PO's memory wiped, check.
Still left some unanswered questions, though. Like, how come Uncle Owen didn't recognize C-3PO, who he had apparently grown up with (after Anakin left him on Tatooine and his mother married Owen's dad)? And what are we now to make of the touching scene in Return of the Jedi, when Luke asks Leia about her (their) birth mother, and Leia says she remembers her being filled with sadness... since we now know that Padme died in childbirth, so Leia never actually knew her at all. And since R2-D2 didn't have his memory wiped, how come he never bothered to mention to Luke anything like, "Dude, that's your sister you're kissing..."
