Matt Ryan's portrayal of the titular occultist has become a fan-favorite casting in recent years. However, his acting clearly hasnt helped get the ratings higher. It's no secret that after Constantine's abrupt production halt last year didn't look good for the show. With rumors of moving the show to Syfy, another network buying it, and the obvious cancelation, it looks as if it's fate has been decided. It has recently been confirmed that the show has been canceled by NBC. There is no word yet on if it will be moved to SyFy but I honestly wouldn't hold my breath.
John Constantine, a demon hunter and dabbling master of the occult, must struggle with his past sins while protecting the innocent from the converging supernatural threats that constantly break through to our world due to the "Rising Darkness". Balancing his actions upon the line of good and evil, Constantine uses his skills and a supernatural scry map to journey the nation to send these terrors back to their own world, all for the hope of redeeming his soul from eternal torment.
UPDATE:It looks as if the source might have misspoken, although at the moment, the details are still fairly shady.
