William "Bill" Finger was an American comic strip and comic book writer best known as the uncredited co-creator, with Bob Kane, of the DC Comics character Batman, as well as the co-architect of the series' development. In later years, Kane acknowledged Finger as "a contributing force" in the character's creation. Comics historian Ron Goulart, in Comic Book Encyclopedia, refers to Batman as the "creation of artist Bob Kane and writer Bill Finger", and a DC Comics press release in 2007 about colleague Jerry Robinson states that in 1939, "Kane, along with writer Bill Finger, had just created Batman for [DC predecessor] National Comics".
Film and television credits include scripting The Green Slime (1969), Track of the Moon Beast (1976), and three episodes of 77 Sunset Strip.
There are a couple of stories that are pretty good and the notable story in which Batman is deputized by the Gotham City Police Department, so he is no longer considered a criminal, but overall this is just another bookfull of Golden Age sludge.
There's really not much to say about this. It is exactly what it is, early Batman comics. They're long (because of the way old comics were written), goofy (more so than the 60s tv show), and meant for kids. It's a fun thing to read but it's not like you need to read this to understand anything about Batman or get a better understanding of the history of comic books.
