I tend to agree with some of the people who say that George lost his way. The original movies had problems and limitations that made it great. It becomes painfully clear watching any Red Letter media video on the prequels.
His constantly re-engineering and tweaking things shows he is a businessman. He lucked out so much on getting merchandising rights for the original trilogy.
I like Star wars as much as the next person, but realize when someone is trying to get me to fork over money for a little tidbit of "extra" stuff. I kinda liked the remakes a bit at first, but after thinking and spending some time, its just eye candy. It detracts from the original story too much.
The added scene did look like it broke flow and gives us too much information. It ruins the tone of seeing Luke enter Jabba's Palace and we're not really surprised when Luke whips out a light-saber on the Sail barge.
It might be nice to set the eerie feeling of Luke being seduced by Vader, but part of the mystery and tension of not knowing what Luke has been doing between movies is snuffed out when we see Luke with a lightsaber early on and then wonder why he didn't kick ass and chew bubblegum in the Palace. Oh yeah, that's where he hid the light-saber, In R2D2..eh.
Maybe I'll buy Star wars again, perhaps when they put all the cutting room floor clips in or make a super 16Ki "Theatrical Edition"... sometime in the summer of 2152.
