Hi Alexandra,
I saw them in Royce Hall at UCLA, and loved them. Definitely a dance highlight of this year, if not of all my dance-seeing time. Their commitment and technical ability impressed me most, as well as their courage to put relatively challenging work on stage. I wrote more about it on Criticaldance:

Hope it's OK to post a link there here.

(in light of Alexandra's clarification below ...)
In summary, I liked Forsythe's Steptext the most, with its contrasts (movement style, sound vs. silence, order vs. disorder) providing a lot of interest, though like Alexandra, I found its dance-rehearsal scenario a bit self-conscious. Wheeldon's Mesmerics was physically beautiful and very well-polished, building up the vocabulary piece by piece before putting it all together effectively for the finale. Torsion looked like one of those difficult things that don't make me envy the people doing them, but you know someone has to do them. My analogy was like watching the great pyramids being built --- you're awed by the effort and difficulty, and by the result, but you probably wouldn't want to do it. The show was also challenging, and engaging with GPD being wonderful exponents of whichever choreographer is lucky enough to have them represent their work.
I got to ask Christopher Wheeldon at the San Francisco Ballet performances in LA about future work he's doing with GPD (as well as trying to put in a good word about GPD), and he said that they're going to work on something new next year. Hooray! Here's to looking forward to their continued collaboration.
