Why anyone would be surprised about this is beyond me.
As it has been said before, it's first week of previews in March of all months. Not only that, but it's a revival that commercially speaking makes absolutely no sense. I have no doubts that when the reviews come out, it'll see a nice bump but it wasn't a sell-out at City Center and it won't be a sell-out on Broadway.
