This story takes place shortly after Battle for the Cowl, and as such stars Dick Grayson as Batman, with Bruce Wayne apparently dead (see Final Crisis).
There's a good deal of pretty well-done emotional stuff in the pages of Long Shadows, with Alfred and Dick Grayson especially, dealing with the loss of Bruce Wayne. The dialogue's well written and compelling in my opinion-- both with the grieving allies and the rogues.
Rogues include Two-Face in a large and quite impressive role (if you're a Harvey Two-Face fan, it's a good one, with some very memorable moments and images involving him). Other big hitters are The Penguin and Black Mask II, both involved in angry, shadowy dealings and backstabbings, as per usual. Minor villains include Doctor Phosphorus and Scarecrow, but they're bit-parts only.
So. It's dramatic. The emotion is moving and well carried out near the beginning, and the plot gets very climactic near the end. That said, it misses out on the five-star rating, because it's not a definitive title. There are greater plotlines out there, with greater drama and greater character development. Not by any means a bad one, though.
