I'd love to see a DH film. I'm a huge fan of the character, and have his entire solo run.
I think DH's second costume would work best in a movie personally.
You can read the scriptment deathshead2 was talking about at
http://www.knightmare6.com/index2.html, under the "Writings" category. Honestly, it relies too heavily on the comics. Scenes are ripped directly from the first 23 or so issues of DH's solo series, and considering that DH's series, while good, was not exactly classic, it hinders the treatment.
At the core, Darkhawk is a spin on Spider-Man. Whereas Spidey is "With great power comes great responsibility," Darkhawk is "With unlimited power, where does one's responsibility end?" Darkhawk struggled with what his power meant. Does he take the law into his own hands, or aid authorities? How far is too far? That theme could make for a great film.
Playing up that internal conflict can mask the problem that DH's rogues gallery is severly limited. He definitely co-opted villians from other heroes in the crossover-happy 90's, especially Venom. Crimelord Philippe Bazin is probably the best villian he has, and he's simply a power-hungry mafia stereotype.
The whole amusement park thing could be excised. I always thought that storyline played out badly anyway. Chris thought his dad was taking bribes from the mafia, when in fact, a bunch of cops pooled up money and bought a suit of armor from AIM and were going to go vigilante with it. Chris' dad was down at first, then changed his mind. All Chris saw was his dad getting his money back.
