Hey guys. Long time reader, rare/occasional poster, so forgive me for trying to cover my opinions on the last 20 pages in this post:
Overall, I think Bob has excellent vision for what this movie should've been and still could be. For the most part, I agree with his decision making.(Do we refer to Bob in the 2nd or 3rd person here? Cause I'm kind of talking to everyone, but Bob mostly)
Order 66 - IMO, the only words Palps needs to say are, "Commander, execute order 66." I don't see Palpatine knowing(or caring) about a clone's name, I don't see the "The time has come"(like Cody and Palp have been planning this together or something?), and I don't see a need to explain what order 66 is(kill the jedi). A simple, "Commander, execute order 66" not only shows Palp's long, long-term plan coming to fruition, it shows that the order is a manchurian-candidate type subconscious order, not something they've sat down and planned together, and it also makes the scene the opposite of one of Lucas's main ways of ruining things - overexplaining things that are best left unsaid. Try it out in your head - "Commander, execute order 66." Nothing else.
Lightsaber switch - again, less is more, do the opposite of what Lucas would do - the glowing red drawer on the desk is plenty. Also, I see no reason to make any fuss out of the switch. Besides the fact that there's no reason to throw out a perfectly good lightsaber, Vader kept the old one simply because he remains conflicted - throught the trilogies, how many people still "felt some good in him?" The old saber being with him symbolizes that, and is surely what Obi would want to take from the duel, either as a memento of his lost friend, or with plans to give it to his son someday.
The killing of the younglings - the way I think of this scene is that it is Palpatine putting Anakin/Vader immediately into a situation from which there is absolutely no turning back. Even Mace's death could've been whitewashed somehow, but slaughtering the kids? No way, Anakin's now on the dark side for good. A VERY necessary scene, as is. If anything, take that closeup of the tear running down his cheek on Mustafar, and put it this scene instead. But the scene has to stay, IMO.
Overall, I'm really enjoying what's been done so far, but there are too many spoilers! Less youtube updates, I feel like I'll have seen the whole thing before it's done. Less updates, more suspense. IMO.
