Forgot to come back to this.
So did finish Y: The Last Man about a week ago. To put it simply, very good series, I was quite satisfied with the ending. My first reaction to there being no further explanation of the plague was mixed as I said before, it felt a little too preachy to be scientifically plausible with proof being plentiful yet ambiguous. But after reading a comment by the author, saying that he didn't want to give ppl a definite answer, instead providing many version of what could've caused it, with one being more plausible then others, and letting readers choose for themselves, it made me respect the writing more.
Besides, the plague was just a catalyst for the story, a means to drive the story forward and give characters purpose. Each individual was strong enough to stand on their own, and (speaking for myself at least), all believable and likable.
There were some moments in that final volume that shocked me and moved me. Heck there were moments in the entire series that warranted an emotional response, so kudos to that. Not even an ending that came across as purposefully controversial or gratuitous, really don't think I could've written it better.
Overall, highly recommended reading.
Then last night also decided to start reading volumes of the Amazing and Ultimate arcs of Spider-Man I have, starting with the first volume of the rebooted (if you could call it that) principal Spidey line, Coming Home.
Wow, what a start. This was pitch-perfect, textbook Spidey. The dialog was sharp, having me chuckle quite a bit with some brilliant Spidey-quips, something I've really missed. The art itself was solid, despite the simpler, day to day activity scenes of Peter going about his business. Ultimately the volume starts of the series with a bang, beating Spidey to a pulp, nearly killing him and having him mend his wounds, not to mention taking a few risks that really feel like they'll pay off (which I won't spoil).
I'm sure there will be volumes that won't be as good, what with different writers and artists taking their stab, but I for one am glad to be returning to the series, and look forward to reading more of my top comic love

.
I'd recommend it to fans but not to anyone else since it's a heck of a commitment. This is Marvel's flagship moneymaker, and to follow such a long standing line can be quite (financially) daunting.
Even I'll be reading this intermittently in-between other series with shorter runs and conclusive ends, picking up sequential volumes at random.
