A fan’s notes, part 3:
Lucas inserted a visual joke in having a scene set in opera house. The “space opera” within a space opera, geddit?
Seriously, though, I see a serious, very familiar filmic archetype at play for the first time in “Sith” – the vampire movies! Think about it: the Chancellor’s seduction of Anakin is structured like the classic seduction of a PYT in a Dracula movie, with Palpatine’s subversive suggestions the rough equivalent of a vampire’s bite. I could be wrong about some of the details; I’m having some trouble recalling just how many meetings there were between Anakin and Palpy, and whether they were all at night. (Ideally, there should be two, before the final, fatal "bite.) IIRC, they have two increasingly sinister rendezvous on as many successive nights: the first, when Anakin reports to Palpatine’s request for a meeting; the second, when Anakin surreptitiously meets Palpy at the opera. After the latter, there’s a prolonged, poignant sunset meditation scene with Anakin and Padme silently communing with each other across Coruscant. This is the last time the two lovers will be on the same wavelength, and it’s Anakin’s last sunset as a Jedi. That night, he will be transformed in spirit, as he will be, after Mustafar, in form.
Also as in some vamp movies, the beautiful victim doesn’t become a creature of the night without waging an internal struggle, marked by ambivalence and anguish. There’s much emphasis placed on Anakin’s obvious regret for losing his innocence. He’s seen tearing up on at least three occasions, when he’s contemplating either losing Padme or turning to the Dark Side, and when he’s massacring the Younglings and the Federation guys.
Likewise, as in the vamp flicks, the victim’s betrothed and best friends put up a spirited resistance to the growing menace, anxiously charting the progressive decline of the specially-selected victim, and exhorting [her] to resist temptation, turn away from the Dark Lord, and return to the sunlit world of all that is decent. One point that many fans debate is whether Anakin could return to the ways of the Jedi after his pledge, and at what point his fall has become irrevocable. I liked the way Lucas dropped teasing hints that this remained a possibility until the very end. Even during the duel on Mustafar, the dialogue becomes ever more heartfelt, intimate, and confessional. Even when their fighting is almost at its end, Obi-Wan tries to get Anakin to see that Palpatine’s “evil,” that a true defense of the Republic requires turning on the Chancellor. It’s only when Anakin shouts that, from his point of view, it’s the Jedi who’ve turned evil, does Obi-Wan give up: [paraphrased] “Then you truly have turned to the Dark Side”.
