I first saw the show in Oct. After 15 minutes, I found Rylance more an annoyance than anything else. I didn't dislike his performance - I just tired of it. I thought Pierce was the best part of the show, even though the role of Elomire is thankless. The scenes between he and Ms. Lumley were very good. The Canadian gentleman that played Elomire's sidekick (whose name I have shamefully forgotten)was also very good.
All in all I thought the performances were good. It's the play that's bad.
