It's one of the better new books DC has put out lately, which usually means it'll be cancelled shortly. I like that it's pretty much just a "what if" about normal folks suddenly getting superpowers. The stories range in tone and theme, but quality has been very consistent. The art, I like it, but I realize that not everyone will. The covers are amazing. It's been very solid and entertaining so far.
One caveat, it's a concept that could get old really fast without an overall arc. I can only hope that some sort of overall framing story begins to appear.
