It's more than obvious that these fans are driven solely by the name of the show and not its actual artistic, technical or entertaining characteristics.
Don't get me wrong. Exactly the opposite is also happening. People who think that this is a series about Satan, the source of all evil according to Christianity are also wrong.
This simple low budget TV show isn't about the devil at all.
The depiction of Lucifer is (increasingly) that of a nice guy. A guy who cares. Who wants justice and he doesn't lie. And he is misunderstood. Someone who forced by the hand of his father to take a job he didn't wanted...
So, again, this is not a series about Satan. It doesn't involve killing, bloody sacrifices and rituals, deception and lies... Lucifer doesn't want to take over the throne of God and rule in his place.
So, why people are so willing to defend it in IMDb's boards, and insult people who see it for what it actually is, a buddy cop show with a twist? Honestly other than the name I can't think of anything else. It has a few somehow fun yet very simple moments: a cute kid with his face covered with chocolate denies she ate any, Nina Simone's Sinnerman is sang by the lead actor...but not to justify the continuous 10 out of 10, I'm reading. It might be a little justified by the young audience who lacks experience on TV series and movies.
In this 6th episode you get some more insight about the things I mention earlier: The Devil is a good guy, truthful and caring, heartbroken by the injustice of a cruel father. And the buddy-cop relationship gets even stronger. And something of value is stolen by an actual bad guy that will monopolize the interest of the young fans.
Overall: If you want to make a show and call it Lucifer or Satan or Master of all evil or ...whatever... you must also be willing to stand up to the hype of what you are doing. Lucifer isn't a thriller, or a horror show, and it doesn't promote to be evil at all. Quite the contrary...
Sure, Lucifer vacationing from Hell to become a consultant for the LAPD seems like a tragic waste of time and talent; everyone expects Lucifer to be the Bad Guy because...you know, he's *Lucifer*. Lucifer turns that premise on its head, so leaves a lot of people confused.
It's not a simple buddy-cop series. Sure, on the surface you can take it that way, and find it to be quite enjoyable. But when you look at the characters (or Main Character), it's a lot deeper...asks or presents a lot of questions that deserve some consideration. Christian canon and dogma may gloss over the issues, but...God created the angels and they were *not* given free will; it wasn't until He created humans that free will got added into the mix. So how could Lucifer 'rebel' if it wasn't God's Plan? Did God need a Bad Guy and Lucifer, being the 'favored' creation/son, was tasked with it? If God gives you a nasty job with certain instructions, are you a Bad Guy? Or a guy doing a dirty job he has no choice regarding?
In this episode we get a huge clue: Dr Martin asks if Lucifer is evil, or others just see him as evil? Nobody wants to be punished, after all...
Can the guy in charge of punishing others for their sins find redemption? Can he give it up, let someone else do the dirty job? Can he create his own identity free of his family's vision?
That's the deeper questions this show flirts with. So far, I think it does so quite well, but if that's not your thing...it's still a fun buddy-cop series, reminiscent of the early seasons of Castle.
