I haven't had the extra cash to really keep up with comic books since I was in my early 20's (many many MANY moons ago), so every now and then, I get a wild hair to *ahem* acquire digital copies of big comic book story arcs and binge-read them. Right now, I'm enjoying a Marvel cross-title story arc from 2011 called Fear Itself and following it with what looks like the arc that followed it, Shattered Heroes..

I've had a blast binging various arcs like this, Marvel's Civil War, DC's Blackest Night, etc.. So what are some really big story arcs you've read that you'd recommend as must-reads?
