I don't know what the Kennedy Center was thinking when it released those videos. The performances from Block and Klena that I saw yesterday were leagues better than that.
I'm with Jordan and the others who appreciated Block's new approach to Norma. She was just so funny and lovable in the first act, and that added some real pathos to her decline in the second act. It was Klena, though, who really surprised me. It seems like he's played a lot of joyless, unsmiling characters, and he really showed that he can do more than that here.
In the supporting roles, Gunn was the vocal powerhouse you'd expect. I didn't love Cravalho's performance; her relative lack of stage experience definitely stood out to me. In particular, her spoken dialogue didn't come across as very natural. Of course, the talent is undeniable, and perhaps her performance would be more fully realized if she had more time to work on it.
The set, I thought, really was poorly designed. Not because it wasn't fancy enough, but because it blocked parts of the stage for probably half of the orchestra section. The two staircases would only be fully visible from near the center of the auditorium, as would the area behind the orchestra where some scenes took place.
Finally, despite what Block said in the interview I posted the other day, there was no discernible "concept" imposed on this production. It was a very straightforward presentation of the material. The only thing I noticed was that Betty jotted things down in a notebook throughout the show. I don't know what that was supposed to mean, or if this was indeed part of the director's concept, but it was completely unobtrusive.
