The performance was really astonishing (marvelous leading singers' voices, decorations, actors' outfits) but there are five things which I constantly dislike.
The navigation, all signs are written in Russian, only.
The subtitles, what was gotten to those who translated the screen play? It seems like a set of words which are poorly translated. It works only to get the general idea. I hope the Russian version is much better.
The audience, right at the end of the performance some people jumped out of seats and headed to exits. It seemed like they were sick of it and finally happy to leave.
The cloakrooms, someone in queue can easily hit you or give you a refreshing punch into your back without any excuses.
The staff, I've read nice feedbacks about eng speaking staff at Marinsky. However, it didn't work to me. All staff members which I had a chance to refer don't speak eng or hardly squeezing words. Google translator n gestures helped, only.
