Batman #17 (2011)

 It's the conclusion of 'Death of the Family', and it was spectacular.
No spoilers here folks. When this storyline began it felt like an 'instant classic' and now that it's completed, it still stands out as one of the best BATMAN stories in years.
Jaw dropping artwork, multiple ohmygodwhathappens next pages and some of the best Joker dialogue ever. While you could certainly have done without many of the 'tie-in' books - this final issue is not one to be missed, but rather savored and enjoyed.
