More than just a little bit of the movie was based on his work. Miller is a genius not only for his work on Batman, but also Daredevil, Sin City, 300, ect. Sin City is just brilliant, and Daredevil wouldn't be nearly what it is without him. But yea, his work on Batman is awesome as well.
Is Holy Terror, Batman even out yet?
Frank miller is da bom. I love his work. He makes some good batman stories, but he's definately much better suited off for SIn City. Having said that though, who can forget 'the dark knight returns.' Miller resurrected batman from the stupid "biff, pow" outfit, to the original darkness that we all love. He snowballed the darkness of the bat, and we all owe him that much.
Must get that... LOve & War and Born Again are f**king impossible to get hold of nowadays, despite (taking most peoples' word on Love & War, while Born Again is one of the greatest comics EVER) being fantastic... though I do hear there will be an accompaniment to the Miller Daredevil Omnibus with Born Again, Love & War and... something else... Elektra Lives Again maybe??
Frank IMO is one of the best writers in comic book history. His Batman as far as character and personality is my favorite and it's how he always should have been portrayed, the way he illustrates him is my 3rd favorite. Mike Meltzer's being first and Jim Lee's being the greatest(good god Jim Lee just owns).
