I have watched most of this on YouTube. There is no problem with the singing. The stage direction is another matter. Rather than a group of impoverished artists, the opera is now apparently about a group of homeless drug addicts.

Maybe these egomaniacs should just eliminate the singers and orchestra and take the stage in a solo performance and see how many people are willing to sit through their nonsense.
The stage director, Damiano Michieletto, is the sort of idiot, who if he had access to the Louvre would probably paint the Aphrodite of Milos/Venus de Milo dayglo orange. He doesn't have enough talent or imagination to design a stage routine for Lady Gaga. I'm sure he thinks that he is the greatest genius to ever have lived. His mama told him so.
I'm certainly not opposed to different interpretations. Nevertheless, there are certain touchstones that are a basic for any dramatic production -- sung or spoken.
Jean-Pierre Ponnelle, noted French opera director(19 February 1932 - 11 August 1988), is my Gold Standard. He understood that the director's job is to tell the story and reflect the music. Individual [Ego?] creativity starts only after the opera content, words and music, is served.
CONCLUSION: If you don't already own one or more Bohemes, buy a first rate CD.
