Question: is there going to be a season 2 of constantine?
Answer: The series aired on NBC from October 24, 2014 to February 13, 2015, over 13 episodes. On May 8, 2015, NBC canceled Constantine after only one season due to ratings not up to NBC's standards, though Ryan has said in the past, that, were the show on another channel, the ratings would have been comparably high.
