I thought it was pretty good, better than some of the artsy stuff that usually pops up during the various ceremonies. I thought the scroll was impressive, as well as all the coordination shown by all the various performers, and not just the tai chi masters. The torch lighting was great too.
I hope people watching in other countries had better coverage than the lousy coverage NBC provided in the States. They always show the stuff poorly, and it takes me all of 5 minutes to tire of Costas' inane commentary over what's taking place. They handled the parade of nations as poorly as they usually do. This time they had the bright idea of putting the names of countries about to enter the stadium in tiny orange letters on a bright red background; I could only make out about half of the names. Dumbest editing gaffe: as the British team entered the stadium, NBC cut to a shot of Nicolas Sarkozy in the stands. Yeah that's right, they covered the British team by panning the president of FRANCE.
