If I had just performed Hamlet I'd preen and enjoy the applause!! It's had good reviews and he is apparently one of the highlights (not just for the fans). I think he is entitled to bask in the applause for his performance. (I know you aren't saying he shouldn't)
My beef with it was always different - the readymade rehab from Uncle Ken and the problematic relationship of that objective to the fundraising objective, plus the "strange" way thag there turned out to be a show a week for all the mates, agents, hangers on etc.
Thank you for the insight that we are getting an edited perspective with the fangirling elements front and centre. I think you are right and that it's skewing perspective. Written like this Coriolanus would have been all about the shower scene and the snog with Aufidius (though there is textual support for the latter). It didn't feel like that when I watched it.
