I loved both the concept and the execution. The best thing about this graphic novel in my opinion is character work, although I do like the storyline as well. The drawing style is beautiful and is giving the whole thing an extra oomph.

Music only became essential to my life when I got to my teen years. I spent hours watching MTV when the "M"" meant "music" instead of "more reality shows than you can shake a stick at".
I was never into the kind of pop fandom that bordered on hysteria - the precedents for something like that to happen in adolescence exist and a kind of idolatry for pop stars is not new and sometimes to the point of treating them as almost divine.
"The Wicked + The Divine" takes that idea and assumes it as  reality. 
There is a centennial event called "The Recurrence" from which emerge people who are believed to be gods. These so-called gods present themselves at events where, allegedly, they perform miracles and seduce the masses - almost like some concerts feel like religious experiences. As expected, this type of situation is not universally well accepted.
It's not the first time that Kieron Guillen and Jaime McKelvie delve into  pop music fantasy ("Phonogram"). Guillen introduces us to a new world filled with interesting characters with well-defined personalities, although there are some questions of logic that have been sacrificed for the sake of story needs (the legal process happens in a way that isn't, well, realistic, even in a fantastic world).
McKelvie's art is "clean" and pleasant to look at  and is specially well complemented by the colors of Matt Wilson.
"The Wicked + The Divine" starts off well, with a mistery at its core, begging for answers that can only be resolved if you keep reading it.

Although I am fully aware that my reading experience would've been richer with more mythological foreknowledge, I enjoyed the collection (and Luci! Oh, Luci) enough even without that to give it four-star credit.
