Since Lucasfilm was obviously paying a hell of a lot of attention to ROTJ for the Blu-Ray edits, I hope they fix the lightsaber strikes. I was watching ROTJ today (I've become very interested in it after all the hooplah going on) and here's what the critic in me wants to see fixed:
1. Nearly all the lightsaber strikes have no effect on anything! For example, when Luke slashes at people on Jabba's Barge, there's no glowing mark. Similarly, right before he chops off Vader's hand, he hits a bunch of railing and the railing doesn't get cut in fact. There's not even a scorch mark! It degrades the saber to being just a normal sword, in a way.
2. Right as Luke is looking at his gloved hand after defeating Vader, gaps appear in the white core of his lightsaber. It's like his lightsaber is shortnening out (maybe that's why he tosses it aside?
3. In the moment leading up to Luke chopping off Dad Vader's hand, you can see both their shadows on the floor in an aerial shot of them. However, you can also see shadows of their lightsabers. Is this supposed to be like that - do lightsabers make shadows? I thought it was established they didn't. Oh well, I'm sure George knows.
