I have not seen this production, so I am basing it on the two minute segment. When I wrote that they are not having fun, it has nothing to do with the seriousness of each character's blight, rather their enjoyment of being on the stage at that moment. It seems dour. Elizabeth Taylor owned the stage and had broad gestures (think Liz in Taming of the Shrew). To me the text should crackle, and I didn't get it from this two minute video. Just my opinion.
