NR, you need to read Saga.
By not reading Saga, you're missing out on a cultural moment for comics as it happens. How often does a new comic come out that sparks such a massive chord for readers, and actually enters the pantheon? It's a few years old already, but I'm pretty sure that Saga is headed for classic status.
There will eventually be a movie or show. No question. And it's already permeated pop culture more than I even realized.
It also reads like a novel -- a really weird, really fucked up, super-adult novel that no child should ever read or look at, but a novel nonetheless. It's been ages since I last read a new title that I've recommended to so many people.
SAGA!
