I think the show is relatively critic-proof at the box office, at least for a good while. They bought themselves a lot of good will with their marketing, which has been measurably more clever than the show itself.
I think ironically, the show's biggest faults result in the creatives thinking their material was critic proof. They were too clever by half (or more than half, perhaps) and lost the thread under the mounting pile of references.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
