Assuming you didn't cancel your preorder that is.
I found that watching the movies in their entirety vs. obsessing over a 30-second clip showing altered footage are two completely separate things. Both the new Krayt dragon call and the notorious "NOOO" in Jedi really weren't that big a deal. They happened, and the film moves on.
Truth is, these films look and sound completely amazing, and it was really great to see them all as one complete saga. The original trilogy looks much better than I expected, and even though reviews say Phantom Menace is the worst-looking, I still found myself staring in awe at how clear and detailed it looked. $80 well spent.
