Gotham and The Flash survived after debuting last year, but Constantine sadly did not. There are a lot of reasons for that, and despite the best efforts of fans and those involved with the show, a second season won't be happening on NBC or anywhere else for that matter. Star Matt Ryan has now taken to Twitter to thank viewers for their support (he's about to romance Keira Knightley on Broadway, so try not to feel too sorry for him), while production designer Dave Blass tweeted a photo on Wednesday of the set being torn down. Are you guys going to miss Constantine?
