I loved Manon! Anna Netrebko was fantastic, and Piotr Beczala kept up with her every step of the way. What a good pairing! The flexible set was rather drab, but it did make a good background for the elaborate costumes. I knew only three arias from this opera, but the rest of it was melodic and quite satisfying.
Only one thing I did not like, and that was the ballet. Movements that were meant to be in unison quite often weren't...the dancers didn't all start and stop at precisely the same moment, arm positions didn't match, etc. The dancers were clearly underrehearsed. But fortunately the ballet was very brief, only a few minutes, and the rest of the opera was just grand.
