Rat Queens

Good afternoon, gentle readers!
Today, I want to talk about Rat Queens, a fantasy comic from Image Comics produced by Kurtis J. Wiebe and Roc Upchurch.  The book follows the exploits of a group of female adventurers: Betty, Dee, Hannah and Violet.  It was nominated for a 2014 Eisner Award for Best New Series and may soon be adapted as an animated television series.
I've heard of Rat Queens, but never read it until last night. I was wandering through my local bookshop when I came across a copy of the trade paperback and bought it on a whim.
The book is very much an adult fantasy with a breezy narrative and uncomplicated characters. That, I think, is its strength and its weakness.
On the one hand, it would be very easy for new readers to jump aboard.  However, there isn't a lot of substance to the series, either, and I can't honestly say that I feel any strong desire to continue reading it. If I did, it would be solely as trade paperbacks and not as a monthly title.
On a scale of 1 to 10, I'd give Rat Queens a 4.  I wouldn't add it to my subscription at my local comic shop, but might glance at the occasional issue on the stand.
