I just have one word for this play: AMAZING. The full company actors were unbeliavably excellent, the voices were astonishing, the musicians were perfect and the atmosphere was totally immersive, you could perfectly relate what the characters were feeling. The subtitles were also working perfectly: the actors were speaking in French but the subtitles were in Czech and English, it's definetly the opera I would most recommend to see in Prague. Furthermore, even the seat I took was "poor visibility" in the gallery, in the National Theatre, you can clearly see everything, there is just a little risk that you might have a column in front of you, blocking partially the view.
