Do you remember what the original program was advertised as when tickets went on sale and how long afterwards the program changed? I'm not a fan of bait-and-switch in general, even if there's a disclaimer that "Program is subject to change."
Two of the three works were based on the choreographers' previous works, all of which had been reviewed. I haven't seen much to suggest there was a substantial difference in the versions Osipova and Vasiliev danced: if the choreography was good before, it is unlikely these versions are bad. If the older versions were weak, they'd have needed work to make them better. The piece that has gotten the best reviews has been the new one. Of course, most of the pieces when reviewed earlier were danced by contemporary companies, with dancers for whom that was their style and who were versed in the technique. I think there is a distinction between bad or weak choreography and bad or weak performances if the choreography.
There is never any reason to assume that even a great dancer will be good in a new genre, especially in such a short period of time. Baryshnikov did White Oak for how many seasons? While the process was interesting to watch, if you like watching the process, even he wasn't notable in much of what he danced after dedicating a lot of time to it.
