I've been interested in Defenders. I really liked the FCBD preview. And while I hate(!) Bendis on straight-up superhero stuff, it felt more like his Daredevil run, which was amazing.
Unfortunately, Marvel's comics are a bit costly, and they don't drop in price soon enough (I buy digitally).
And often, while waiting for the eventual price-drop, their series are almost always cancelled or relaunched before I get around to picking them up. Which leads me to lose interest altogether.
