Was sorry to miss LeBlanc this time around, although I agree she can overdo the sweet guileless smile. I have fond memories of her and Roman Rykine in this.
Oh, I remember their partnership, too. It was lovely. (Whatever happened to him?) Another favorite, in 1999, was Lucia Lacarra (sp?) with Yuri Possokhov. I hated to see her leave the company. She had amazing feet.
The most memorable Giselle I ever saw was back in 1976 -- American Ballet Theatre with Natalia Makharova and Baryshnikov, and Cynthia Gregory as Myrtha. Tickets were cheaper in those days, and when ABT came to town (back then they performed for 8-10 days in Berkeley at Zellerbach, and then 8-10 days in SF at the Opera House) I went to every performance. I saw all the casts of Giselle, and this cast more than once. But there was one night when everyone was so "on" -- I was so moved I could barely speak. All these years later and I still remember it vividly. That has ever after been my yardstick for judging Giselles.
