As a kid, I had little familiarity with Marvel's mutants, having first seen the original team in a reprint of Marvel Team Up #4, but my first exposure to the "All-New-All-Different" variety came with Uncanny X-Men #147. By then, I had been reading comics for some time, and this was a fascinating new group I'd barely been aware of, but I was immediately intrigued.
I don’t follow the X-books anymore, but I can get the gist of what’s going on at any given time. If you’re a big enough fanboy, you pick up this stuff through osmosis. From Previews and the online material I’ve read, I know that the future is a nightmare, the mutants are fewer and more hated than ever, and hope is even more distant that ever. So business as usual then. And Cable is running around with a little baby girl strapped to his back that will be prematurely aging into Jean Fucking Grey in the next 18 months or so.
I'm with the Scarlet Witch: No more mutants for me, thanks!
