I'm just getting into reading comics for the first time, and I'm reading various bat-family comics starting from New 52.
While I have researched where/when to read each collection from each series for the most 'complete' story-telling of Batman's adventures (and got great tips from some nice folks on this forum!), I'm a bit confused about what the overarching theme of 'Batman: The Dark Knight' is...
I have read that, for example, while Batman is of course heavily focused on Batman, Detective Comics includes more heroes in its focus, and of course Batman & Robin focuses on the relationship with his son.
But then what is 'Batman: The Dark Knight' about? Why aren't those stories in either 'Batman' or 'Detective Comics'? What sets them apart in a separate series?
Thanks!
