This is merely MY two cents
What should the concept be?
Likened to Hulk, we've seen and know of his transformation which could be shown again through Flash backs at points in the movie. Get to a good story of DareDevil that makes you feel your IN the comic. Dare Devil is griddy, dark, and needs a serious tone.
The setting: RYKERS island, which is where the movie starts. A man there is unjustly acussed of smuggling drugs. This man, is a key whitness to a case to justify Kingpin's presence in Rykers, Only there for the soul reason of hopefuly ending him there in prison before he can testify. On the day Matt and Foggy see him to tell him that they have evidence to set him free, a prison break insues. Matt becomes the Dare Devil, and makes his way into the prison to get to the whitness. Consiquently, one of the escaped prioners, is the homicidal BULLSEYE who goes out of his way to find and end this whitness.
Before he gets a pencil in his back, the whitness tells DareDevil to tell his Lawyer, to look up a private detective he hired: Dekota North, she was following leads to find more evidence in case he got done in.
Matt and Nelson's new perogotive is to see that Dekota is kept safe while she looks for clues, meanwhile Bullseye is back on the streets and is out to get the next loose end. Daredevil/gets close to Dekota while working with her, but is weary because of his recent relationship Karen Page, who as it turns out was killed by Bullseye. Dekota is concerned about DareDevil because he's become more....rogue in his methods since Pages' death, and is worried that he'll become who he hunts.
The director should be big hitter like Tony Scott, or Spike Lee.
Here, is the cast I think can really make this work
Matt Murdock- Micheal C. Hall
Bullseye- Vincent Cassell
Dekota North- Kate
Foggy Nelson- Sean Astin
Ben Uric- Hugh Laurie
Wilson Fisk- James Gandolfini
