Bosch Legacy is on my radar, I'm assuming since Hieronymus left the LAPD Marlo Stanfield isn't in this show.
I started watching Lucifer primarily due to the impressive Lauren German. She was on Chicago Fire in it's opening three seasons, practically set up the franchise it's become. Playing The Prince of Darkness is an actor named Tom Ellis, I've never heard of him before, he plays Lucifer as an irresistible seducterer who makes people confess their deepest desires. He can also call upon a bottomless poll of blackness that causes insanity in those that witness it. He's stuck with a quandary, Detective Decker (German) is immune to his powers.
He's been condemned to rule Hell for eternity, he decides to take a vacation in La La Land. I didn't know The Prince of Darkness was Welsh.
