"Paranormal investigator teams up with angel and young girl to save mankind from a infestation of demons". Sounds like the synopsis of a certain CW show? Okay, like, almost ALL CW shows?
Well, it's not. It's the synopsis of the pilot episode of Constantine, NBC's contribution to the onslaught of superhero/comic book adapted TV shows this season.
Very much like the 2005 Keanu Reeves movie adaptation with the same name, John Constantine is a tough talking exorcist that reluctantly is thrust into a demonic plot and becomes savior of Earth, and sworn enemy to Hell. Except, unlike the film, this version of Constantine is much more faithful to the original Vertigo comic, Hellblazer and the current DC Comics series also named Constantine.
