I'm not actively buying comics currently, but I saw the promo art and some interviews. The concept seems pretty interesting enough: Marvel's own analog to the Fast & Furious meets Ghost Rider. I believe Johnny Blaze is still doing his thing, which is well enough. Jason Aaron's run introduced the concepts of various concurrently existing "spirits of vengeance" across the globe, over the centuries. Also a new Chicano protagonist doesn't hurt. (side note: has DC's Vibe been given a respectable update?)
