I was sold in the first episode as I use the material for a research. For some reason a demonic personality is difficulty one to produce. But even then, I became very intrigued when they showed a large demonic population are the target child. In comparision, Kirkman's Outcast showed also a large demon population, but they made it to happen around the main character.
In this one, demons are far more advanced, and scarier than in the Outcast. Still, these both series are excellent in quality. Although I don't know how they compare to Damien. And Lucifier is battling in its own league. The Exorcist story go way deep into the mythology, without actually being scared on putting on some of Catholic Church practices in the lime light.
It is still too early in the series to know if the quality will drop, when they open up the madness to the wider audience.
