I also love how people can be fully entertained today by a play that was written thousands of years ago. It just goes to show how theatre, despite constantly evolving, has permanent roots. These roots are apart of our heritage and have been integrated into our humanity.
The chorus, just like today's musicals, serves the purpose of keeping the audience informed and invested. Although the leads usually make a lasting impression, the chorus creates the ambiance, mood and overall tone that carries the story. Again, this is something that has been relatively constant since the beginning of theatre.
After reading this review, I was inspired to research these modern day productions of Satyrs and other Greek plays. I want to find out how often these plays are being produced and what their popularity and success are amongst today's public. I researched with little success. However, it seems that these Greek plays seem to be a bit of a "go to" which leads me to believe that they are counted on for a positive run.
Here are some pictures of Greek play adaptations.
