Gotham posted series low at 0.7 last night.
I'll try to not worry too much, because despite the declining rating and Fox's shift to more sports and reality shows, Fox can still move Gotham to Friday and retain a major of its loyal audience. If not Netflix (which last time I heard spends 2 million per episode for streaming right of Gotham) can still pick it up. If Netflix doesn't pick it up, DC new streaming service (where Gotham's producers Danny Cannon and John Stephens are entrusted with the Superman prequel Metropolis) can still pick it up (if they think that these two can create a brand new prequel show worth for their streaming service then an veteran show with established fan base should be given the same chance, right? Right???)
Tl;dr: Gotham likely might not be on Fox on Thursday this fall, but it can moved to Friday, or Netflix, or the DC streaming service can pick it up. There're at least 3 alternatives out there, so I will try to not worry too much.
Edit: Oh and HH last night were 0.7/0.6, so Jerome's return didn't prop Gotham up, like, at all (which comes at no surprise to me).
