The Long Halloween

If The Batman will showcase the Dark Knight's detective skills, then it needs to adapt The Long Halloween. This is the comic book cited by Christopher Nolan as one of the most influential for his Dark Knight Trilogy. And it is very intricate, featuring some of the most iconic characters from the rogues gallery.

However, it is still one of the most highly regarded Batman storylines. Yes, it features a younger version of the superhero. However, it shouldn't and needn't be so on film.

We've already had a terrific Harvey Dent on screen, in the Dark Knight. However, the Long Halloween version would be the most complete one.

Which of these storylines should be adapted in the first Batman flick of the DCEU? Did you have any other(s) in mind?
