Showrunner Daniel Cerone took to twitter to announce the shows demise.
So it’s down but certainly not out and there are plenty of networks and streaming services that could save the show. The hot tip is that SyFy – the sister network to NBC – will revive it.
Stephen Ammell, star of Arrow on The CW, has already waded into the debate, too, saying this on Twitter.
#SaveConstantine -- Hey TV Networks / Netflix and the like... If you pick up the show, I'll guest star.— Stephen Amell (@amellywood) May 9, 2015
The show sees Demon hunter and master of the occult John Constantine (Matt Ryan) reluctantly return to fighting demons and casting their souls to hell after one such hell beast targets the daughter of one of his closest friends, Liv (Lucy Griffiths).
Constantine then takes his considerable skills as an exorcist on the road, traveling the country to find demons and send them back to hell.
So while its bad news for now, there is a glimmer of hope – the best thing that fans can do now is keep tweeting their love for the show and, more importantly, keep watching the episodes.
