I think it's bad.
B99 is not owned by Fox. And like the Mindy Project, it can be canned before season 4 (despite syndication opportunities after 88 episodes) because of it. So if B99 and a bunch of shows aren't doing well, I think it's more likely that they'll cancel it over shows they do own.
Tuesday's right now are already are a graveyard for Fox re: ratings. And being sandwiched between Grandfathered and The Grinder (getting 1.0 and subfractional ratings atm), I'm not really hopeful. At least on Sunday's it got a little boost from football and The Simpson's before it.
I dunno. I'm really sad about this. Mostly because I think the show deserves a lot of seasons and I don't think it will get them. But who knows, maybe it will defy expectations.
