Constantine: TV Series (2014-15)
Dirs. Various | Episodes: 13, approx 43 mins each.
A short-lived live action TV series based on the long-running Hellblazer comic book, but named after its main character, a spell-casting exorcist from Liverpool named John Constantine. It's more faithful to the source material than the 2005 US movie of the same name is, but does still do its own thing from time to time.
In addition to being an exorcist he's also a demonologist, an occult detective, and even a bit of a con-man, if the situation requires it.
On the surface he doesn't seem to be the kind of person it would be wise to put any trust in, but he's a humanitarian at heart. If someone is plagued by demons and they really don't deserve such attentions, he'll often go the extra mile to help them resolve the situation.
If he can smite a demon or two in the process, send them back to the hell that they crawled from, then that's all the better for John.
