John Constantine might not go to hell, but he’s headed straight to broadcast TV purgatory.

NBC has decided to halt production on Friday night’s Constantine, capping the series at its initial order of 13 episodes.

The network says the show is not canceled and could come back next season. But its ratings don’t make a hugely compelling case: Constantine is averaging 4.5 million viewers and a 1.4 rating among adults 18-49 at 10 p.m., coming out of Grimm‘s 6.3 million and 1.8 rating.

NBC has been struggling to find a companion for Grimm on the evening, trying Hannibal (a series with a low-cost production model for the network, which returns for a third season next year) and Dracula. But nothing has managed to break out from a ratings standpoint.
