Within and outside the fandom over the past year, there’s been a lot of chatter about how Netflix might save Gotham. They already saved DC spiritual partner Lucifer from beyond the grave. Today, we’re exploring how and why Netflix might #SaveGotham, and what we can do to make their decision super-easy.

We’ve seen Netflix polishing its cancellation axe recently – systematically chopping well-loved shows such as Jessica Jones, Luke Cage, and One Day at a Time from the platform for fiduciary reasons. They’ve picked up fellow DC property Lucifer, just named the most bingewatched show of recent times.

We’re guessing the price at which DC were selling Lucifer was right for Netflix; we’re hoping they can make a similar deal for Gotham. What can Gotham fans do?

Rewatch

As we’ve said time and again, a great way to get Netflix to notice is simply to open your app and give Gotham a rewatch. Your views count, especially if you then go on to watch another show suggested by Netflix from outside your current watch list.

Re-register for Netflix

Maybe you watched all of Gotham before on Fox; maybe Gotham isn’t supported by Netflix in your current location; or maybe you’re sharing Netflix with ten housemates. Whatever your situation, signing up to Netflix (even if it’s only the free trial period) and watching Gotham is a viable way to get Netflix to notice the show.

You can always use a VPN (we suggest NordVPN) so you can watch Gotham from whatever country your bed lies in. When you’ve registered for Netflix, influence your friends and loved ones to do the same and get them all watching Gotham on repeat.

Take cord-cutting to the next level

After you’ve rewatched Gotham a couple of times, cancel your Netflix membership and very clearly tell them the reason why you’re cancelling and when they can expect you to come back using this handy contact form.Make sure you also do a live chat and maybe even a phone call to tell their customer service bots what’s up. Influence your personal network to do the same; the more cord-cutters there are, the more Netflix will sit up & listen.

Tell Netflix Gotham is the bomb

We know: we’ve all done this a few times before, but there’s no harm in doing it again. Make sure you let Netflix know just how much we love Gotham by requesting they keep Gotham on air, then make sure all your friends and family do the same by following this link.
