I had the luxury of seeing the first preview on Thursday and then coming back for performance 1A, as the production is referring to it, on Friday.
There will probably be some spoilers below.
I think what went on on Thursday may have been one of the most spectacular evenings at the theater I have ever had. The production came together to put on an incredible performance, in light o the circumstances, which I found out Friday were caused by 1 broken caster in one of the revolves. Though many are crediting Jujamcyn with the incredible treatment on Friday, the credit really goes to the producers. Since Rudin pulled out of the production, Warchus, Minchin, and a few of the other creatives are producing the show themselves, breaking the Bialystock rule of "Never Put Your Own Money in the Show." They were doing some incredible service recovery on Thursday, costing themselves tons of money to try and ensure that there was good buzz after the issues.
I really enjoyed the show. I agree with just about every piece of criticism that has been addressed in this thread thus far. You can't go into an adaptation of a quirky comedy film expecting the next Hamilton. You have to go into a piece like this expecting to laugh a bunch and enjoy the show, which I wholeheartedly did. Some of the stage craft, like the car chase sequence and the illusions near the top of Act 2, are among the most impressive moments I have seen on the Broadway stage. After seeing the sung-through version, it was incredible to see the visuals that went with things like the car chase, which seemed like a long music break until you added the black lights, turntables and puppets to the mix.
The show can definitely use to lose about 20 minutes. The plan of the production, per a friend who is working on the show, is to find 10 minutes to cut of actual content, and try to get the intermission down to 15 minutes-It's running at about 25 minutes at this point because of the complexity of the scenic changeover that needs to happen set up for act 2. Though the medical number in Act 1 and Nancy's Song in Act 2 are probably the least necessary to the plot, they have the most of Tim's style in them, and aren't likely to get cut. The show actually only runs 2:15 plus the intermission.
I know there are a number of comparisons to American Psycho. This has a lot more going for it than Psycho did-It has already run in a similar sized theater, and is up for a bunch of Awards in London right now-Andy is likely to pick up an Olivier a week before the show opens on Broadway. Psycho came form a 350 seat fringe theater, got mixed reviews, and no real award buzz. I really want this one to succeed. It is such a tough season since there have been so many really strong new musicals this year.
A word about seating. Thursday night I was in the 4th row of the mezz, house right, perfect view for the 16 minutes of the show we actually saw. When the codes came out for replacing tickets, I jumped at a pair of Row H center orchestra seats, on the aisle, presumably unsold house seats, which provided an incredible view, since I knew what to expect for the show. It might be tough to take in the whole of the production sitting the orchestra on the first viewing-There is a whole lot going on pretty much all the time. I wouldn't sit much closer than I was, as the show deck is really high off the stage to accommodate the mechanics of the 5 turntables that drive the action of the show.
As for merch, 1 t-shirt, hoodie, 2 magnets, 2 keychains, 1 button, mug, and window card.
And yes, they are working on a stuffed groundhog for the merchandise stand.
