The monorail does make any day better!
I'm curious to know what elements of the production you felt weren't true to a 19th c aesthetic -- I agree that this version is very different that most of the Giselles around today, but I think that's more a function of how the ballet has changed over time.
Still, glad you got a chance to see it, and add it to your repertoire!
I won't profess to be an expert or even knowledgeable, but on the plane to/from SEA, i read a book about La Syhphide to put my self in a dance-y type of mood so I had my (probably wrong) image of 19th century in mind. Much of the first act struck me as something one might see in the 19th century, with the moderate height of legs, the tempos, etc (and the tableau at the end), but a few times in the second act, with some entrances and lifts, it seemed more acrobatic (and soviet-styled) than what might have gotten from a romantic 19th century ballet. That's no fault to the company, or peformance, and the program notes even say Boal left in some more modern elements.
But I can say that the spring is ballet high season in NYC--we get ABT's met season, and NYCB--and aside from Balanchine's short Walpurhisnacht where Sara Mearns of NYCB killed it, the piece i'd most want to see again is PNB's Giselle. We thought of getting tix for Saturday night to see Korbes, but it was just so nice outside in Seattle for late spring. ;)
