Actually that might be a show I might try out. Interesting premise and what is so hard to believe? There is a lot that the Bible does not tell us about Lucifer and his leaving Heaven.
A few years back there was a TV series called “Brimstone” about a fallen cop who is let out of Hell by the Devil to help round up escaped souls, it wasn’t bad, but did not last very long. I loved the guy playing the Devil.
Of course if this was about the Lucifer being a Transgender and moving to Earth, that might be something else.
John Glover...he was Lionel Luthor on 'Smallville', as well.
