Netflix’s The Sandman only debuted earlier this month, but fans of the series, based on the comics written by Neil Gaiman have already been eagerly awaiting news that a second season of the series is in the works. Thus far, that announcement hasn’t come just yet and now, Gaiman is explaining why — as well as encouraging fans about what they can do to help encourage the streamer to renew. On Saturday, Gaiman wrote on Twitter that The Sandman is a “really expensive show” to make and that the existing season needs to perform strongly to be considered for renewal.

Because Sandman is a really expensive show. And for Netflix to release the money to let us make another season we have to perform incredibly well. So yes, we’ve been the top show in the world for the last two weeks. That still may not be enough. https://t.co/m7VusGL2rW

If we get a second season. (Please encourage all your friends to watch Sandman. Encourage all your friends who have begun to watch Sandman but got distracted by life to finish watching Sandman.) https://t.co/OvoHY00Xtp
