It was fantastic! It sure looked live up until the last high note. but yes, it didn't look like she was really singing the final note. At that register in her voice, you would've seen some tension in her neck/jaw. You could totally tell that Faith Hill was lip-synching, but it sure didn't matter with Jennifer. Awesome!
I think Whitney's version will always be regarded as the best. Incredibly powerful yet it didn't destroy the song or the lyrics in an attempt to make it her own. It's the NATIONAL ANTHEM. You don't mess with it. Plus, the timing of Whitney's version was just right. We were a nation united that had just gone to war in the Persian Gulf.
