Absolutely...but even a genius has a bad day, I guess. He really biffed that set, but I wonder if he did so at the instruction of Daisy Prince or someone else involved. He really shouldn't be faulted if he was giving the director or the producers what was asked for. Perhaps he argued for something simpler and lost the battle.
I can only guess that the big set was predicated by the larger theatre and a need to fill up the stage and give the folks up in the balcony something to keep their attention. Had the show ended up at the Newhouse, as originally intended, there's no way most of what was seen at the Minetta Lane would have been on that stage.
