I was there tonight, also, front row of the orchestra. This was my first exposure to the play, and I was completely enamored the entire time. The entire cast is so uniformly strong and powerful, it's so incredible to watch them be so involved, and then involve us with them. I think the actress playing Catherine stole the show for me, and I was floored by her performance. Even though I didn't know the storyline, I happily guessed the effect that was going to happen at the end, after seeing what happened at the top of the show. (I mean, white floor, sprinkler system, death threats being thrown around...haha).
The only time the show dragged for me was the "end of act 1", where they're all together in the house having a very tepid conversation. A single beat plays every 4 seconds, and that lasted for 20 minutes. It was effective as hell, but the pacing dragged for me.
Also, I hope the fix the timing at the end of the show with the black box flying back down. It was pretty jerky tonight towards the end, got about half way down nearly unnoticed, and then all the sudden swooshed down in an instant. I think if they can replicate the effect at the top of the show, and have it close as the Lawyer is talking, it will be SO much more effective.
As for the view, it was INCREDIBLE for $20, and I am very happy having not paid $50 for the on stage seating, which is what I had planned to do. When I return, I'll opt either to do the front row again for rush, or the front row balcony, as I would love to see the floor better.
Random, but a butterfly or a moth was flying about the stage and front orchestra for the last 10 minutes of the show, and that was pretty magical to watch.
