I'd like to see a new version of Buck. Not any sort of 'I'M BUCK GODDAMN ROGERS' Frank Miller version (wasn't The Spirit enough classic comic strip to destroy?), but something in the vein of BSG. As someone said, ignore the 1970s/80s version, make it a new adaptation of the classic comic.
If, say Flash Gordon, were to be re-done (again, an adaptation of the original comic, nothing to do with the 1980 movie), I'd like to see it bright and breezy, though not camp. Sort of Star Wars ANH meets Firefly, meets Indiana Jones. But Buck could suit a dark makeover. All his friends and family, in fact everyone he knows, are dead, humanity has survived a nuclear war, there are barbarians at the gate ... Hardly feelgood material.
Of course, even if Millar doesn't mess BR up, we'll probably only get some crappy Sci-Fi channel version, with sh1t special effects, a 13 year old in the title role and a script on a par with teletubbies ... Oh, to see someone do for Buck what Chris Nolan did for Batman.
