The video is focused mainly on that story,however,they also mention Original Sins and how the books influenced the 2005 Constantine movie.

And even though they don't discuss it,I was wondering how popular is John Constantine? he's been around for quite a while in comic books but just recently has gotten more exposure on the CW Legends of Tomorrow and in animation. And that's after the big screen movie and short lived solo t.v. show. Do fans see him becoming a household name -if he isn't already-like other DC characters-Superman,Batman,etc.?
