As regards the intent of the OP... the title of the thread isn't "TIFFANY'S sux! I can't wait 'til it's gone... how long will it last?"
The thread can (and whether it should I leave to the beholder but in the case of this reader, at any rate, it was) be read as simple idle gossip about a production that appears to have less legs to stand on than typically indicates a healthy and long run. Discussing the practical matters of Broadway economics is often fascinating, and need not be considered "mean" simply to speculate as to the comings and goings of shows.
Save "mean" for when After Eight calls people who like things uncultured swine or somesuch. (i.e., unsupported, uncalled-for personal attacks. Or, you know, actual meanness.)
(I hope After Eight can appreciate being appropriated for the purpose of a demonstrative joke at my own expense. He/she/it is often able to support his/her/its criticisms.)
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.
