Rogue's an interesting one! I'm not so wedded to the character as Dredd/Stront/Nemesis, so there's wriggle room, and I think there's room to make a film that could actually reboot the character for the better. That said, I think the main weakness in Rogue was never the set up, including Gunnar/Helm/Bagman, but the way it never contextualised the things that seem a bit GFDy (3 SLOTS - 4 MAN SQUADS!). The otehr problem is it never quite found a way to put Rogue's search into a consistent conflict, where the warring sides and the world felt "solid" - the boundaries of the war, the geography and the stakes.
If Duncan Jones can find a way of not throwing the baby out with the bathwater, we might finally see Rogue live up to the promise that the strip always teased us with. Visually I think its all there in Gibbons/Kennedy/Wilson/Ewins art, and in the 2000~AD tradition of taking the visual and cultural language (in this case of WAR!) and distorting and ballooning it to insane levels. I want to see a Nu Earth that is a true hell hole, but perhaps in some ways a beautiful, chem coloured, crazy, over the top experience - not just men in chem suits and a quarry! hopefully they will have the budget to do that element well.
