Well, the ending wasn't what i expected. After twisting and turning and leaving the reader hanging in the balance for 59 issues Vaughan ends the series with an epic jump into sixty years in the future. The true cause of the plague is never really articulated, so if you're looking for answers for little squiggly questions, you may be disappointed. But the overall arc of the story is an emotional one, and by the end of the book, I felt that Vaughan had moved to exploring more far reaching concepts like the nature of life and death itself. 
 Since this is the last issue of the series let me provide something of an eulogy for Y:The Last Man It has been a tremendous ride and i will continue to stick by the initial analogy i made to Tintin. The eventually storyline maybe had nothing to do with that brave reporter but Vaughan created an almost childish sense of anticipation in me every time he finished an issue with one of his trademark (and often cliche, but who cares) pensive flourishes. 
 It made me wanting to keep reading, keep finding out what happens next and i for one am glad i picked up that copy of Sandman because my foray into graphic novels helped me find Y: the last man. It took me back to younger, carefree days when would pore over Asterix, Archie, Superman, Tintin and a whole host of other comics, examining every detail of the pictures and positively devouring them at a much faster pace than i could afford to buy new ones. 
 So Kudos BKV. Well done.
