This is the first production of Merrily I've seen where Franklin is the main character. Groff's performance is absolutely no joke - he wrings Franklin dry, bringing a fully realized and bizarrely empathetic human being to life where there's usually just a shambling vehicle for the Charley, Mary and Gussie show. Even in the first scene, where Frank is typically at his most offputting, Groff gives Frank an aura of piteous entrapment by speaking low and resigned, and when he tells Gussie that he hates his life, for the first time it seems like he means it.
Part of this is that essentially every character besides Frank, Mary, Charley, Beth, and (mostly) Joe are played like caricatures. This creates a kind of stomach-churning Muppet movie effect, which is a really intriguing way to illustrate Frank's descent into the artificial hellscape of fame and wealth. In the middle of this nauseating paper-thin cartoon bacchanalia are a set of very real people being torn apart in very real ways, and when it works, it's truly startling.
On the other hand, it does play up the faults in Furth's script. Gussie, in particular, really suffers, and I wish that Krystal Joy Brown had been able to play her in a way that felt more grounded. Elsewhere, Furth's dialogue often clunks, and I was a little surprised by how many jokes got a much less solid laugh than they typically do. I was also kind of surprised (in a good way) by moments of unexpected tightening here and there, particularly in the opening of the apartment scene. Even if the dialogue is too often leaden, the book's overall shape and structure is extremely strong, and I can't imagine a first-timer being confused by the plot.
One element that I really enjoyed was the furious pacing. Friedman whips the show along like she's got places to be and it works tremendously well. I've never seen That Frank sung so fast, it was almost a group patter song, as was Now You Know. It helps to boost the show's sense of time slipping. That, combined with the searing performances, means that moments from one scene are always overlapping with the next, and the feeling of choices begetting choices has never landed so hard.
Besides Groff's almost magical performance, Radcliffe and Mendez turn out performances that are far more than serviceable. Radcliffe has long since established himself as a stage actor, and it was a lot of fun to watch him being absorbed in this role. The sheer chemistry the three of them have is absolutely breathtaking. Every interaction is prismatic, giving you the sense of briefly glimpsing a wider range of their lives. When things are rough in the first act, you can feel the cumulative weight of all that's come before them in a way I've never seen, and as such it's agonizing to see exactly how each weight is laid over the course of the show.
I was not expecting the held final note and it ran me down like a train, splitting my heart wide open. It's one of those perfect theatre moments where the show loads you with emotions and guides you to an epiphany that allows you to release them. It dams you up and then blows you apart.
