I was there tonight! I'd say the show runs pretty close to the posted time, though I can't remember when it started exactly, but we were on the street at about 10:35. It definitely started around 10 minutes late because we were still almost to the intersection outside the theater at 7:57 and had a good amount of time in our seats before the show began.
I'll admit, this show just didn't really click with me. I knew essentially nothing about it going in other than that it was a Pulitzer winner and the synopsis posted on its website. I thought the relationship between the two brothers was interesting to explore, but certain issues kept coming up where I couldn't see the point of them (infidelity being a major one). I found the first act amusing but not overly entertaining and the second act seemed to have more of a direction which I enjoyed more, though the ending was something that I predicted to my friend at intermission (but the way that it happened still surprised me). I can certainly see how some of the topics the play addressed would be resonant, but I felt like I left the theater missing a large chunk of the deeper meaning of the show, so I'll be curious to read other people's thoughts, or if they have insight from other productions.
The set was interesting but almost felt underutilized, like I kept expecting something else to happen but it never really did. It was a unit set for the most part, contained on a platform that reminded me a bit of Pass Over's set in a bit of an abstract way. I probably wouldn't recommend sitting in the front row though because of this platform, which looked to be at least half a foot tall, if not a foot, and all the action takes place on there, where a corner of it is positioned quite close to the lip of the stage.
Both actors were quite good, giving a performance that really cycled through a whole gamut of emotions, with a lot of fairly physical scenes as well, and both were very charming, especially when going through the three-card monte schtick. The audience seemed largely appreciative, though of course it was the first preview so that's to be expected in part.
Didn't get a chance to check for merch but I do know there was some. The mezzanine bar was perhaps the emptiest bar I've seen, as no one really seemed to linger on the mezzanine level. TDF tickets were in row B front mezz, which was an excellent view, though very close to the sound booth, which could be something to watch out for it that would distract you (there's a small reading light on the whole time and sometimes you heard the turning of pages but I really didn't find it to be an issue at all).
