Walk down Bat-nostalgia Lane with the fan-assisted death of the 2nd Robin, Jason Todd (later resurrected as Red Hood) and the introduction of Robin III/Tim Drake.
Throw in some classic Joker insanity, a little Batman v Superman action, the mighty Lady Shiva and the awesome artwork of Jim Aparo (with Mike Mignola/Hellboy covers) and it's a winner.
Would be a 5-star except for the minimal extras eg artwork/creator commentaries, etc.
