Sorry if this is redundant but I am really interested in starting the batman new 52 series. However, I would like to brush up on some history so that I have more background information. I do not have too much money or time right now so I would like to limit myself to 5 batman volumes which are best suited to prepare me for the Court of Owls. I realize the vast history of the batman comic and that I am missing out on a lot by limiting myself to 5, but I plan on going back later when time opens up so until then 5 batman volumes will have to suffice. Any ideas? Any from Morrison's run will be more ideal but I am open to others if they are more integral to the current plot in your eyes.
To put it in perspective, I have seen Batman the animated series, all of the movies, and even some of the animated movies such as Under the Red Hood so I do have a decent idea of the Rogue's gallery and such. I have never read a batman comic though.
