I just saw the production this afternoon for the first time. It's far more spectacular in real life than on video (which incidentally looks like upconverted standard definition on our local HD broadcast from KCET).
I'd say that it's by far the most spectacular Nutcracker I've ever seen. Tina Leblanc danced SPF, and I can't enough of her generous, easy dancing. The snow couple (Dores Andre and Anthony Spaulding) were impressive as well. The corps was especially good, too. I was very tempted to stay the night to see Tina dance the grand pas, but that was not to be.
The choreography, especially for the corps, seemed Balanchine-esque in the speed, density of steps, and repetition and building up from simple steps. It's Helgi's best choreography. I'll definitely see it again next year.
Gantz's review is particularly stupid: he complains about trick-filled choreography in SFB, and then proceeds to tell us how Boston's Nut beats SFB because it has better tricks?
