If you don't like violence and some gore, this definitely won't be the show for you.
Other than that, I was unsure after the first episode, but found myself enjoy the drama the more I watched. I liked how kooky and, at times, silly and lighthearted it was in between the darker, more bloody scenes, and also how it lightly explored what it means to be a family and the lengths people would go to, to protect theirs.
Considering the cliffhanger ending, maybe we'll get a second season.
