[ Correction: Constantine - City of Demons was a two episode series (not a six episode series) ] https://en.wikipedia.org/wiki/Constantine:_City_of_Demons

Matt Ryan's Constantine wasn't completely done after the single season cancellation of the show (by NBC). With the character regularly featuring across The Arrowverse, in Constantine - City of Demons, and in several of DC's animated shows.

Fans didn't get more dedicated Constantine in live-action, but perhaps in the end they got even more.

Quote: “Sad news. Thank you #Hellblazers for your support.

You truly are the best.

And thank you to everyone involved in the show.

Memories made forever.

Very disappointed that we are not continuing this journey - will miss playing John.

You guys never gave up. I thank you all #Constantine.”

End Quote. (Constantine Star Matt Ryan in May 2015).
