In prep for the Dark Knight Rises, I hope to purchase and read through the Knightfall story arcs. I know there is a chance the movie may have nothing do with the comic, but I want to read it because of the critical acclaim it has received and the value it has in the Batman history.
Anyway, unlike the Long Halloween, the Black Mirror, and other Batman stories, Knightfall seems to be available in three parts (Broken Bat, Who Rules the Night, and KnightsEnd). I thought the entire story arc was contained in one book, but instead it looks like I have to get all 3 parts. That is one long story arc because each book has, on average, close to 290 pages.
To make thing even more complicated, I see that DC released Knightfall volumes 1, 2, and eventually they will release volume 3. These appear to have more stories than the previous collected editions, but I am not more confused. Which collected editions should I get to read the Knightfall story arc, the one people rave about as one of the best Batman stories?
