6) Dark Reign
Perhaps the most consistent failing of the Marvel Cinematic Universe is the underusing of its villains – with many of the films featuring cookie-cutter bad guys who are hellbent on destruction because, well, you know, they’re bad.
A brilliant way to increase the villains’ role in the MCU would be to adapt Dark Reign, an event comic whose central idea was basically: what if the bad guys won?
Following the Secret Invasion debacle, the arc sees Norman Osborn oust Tony Stark to become the new head of S.H.I.E.L.D., turning it into the more militant organization HAMMER. The corrupt businessman also forms his own team of supervillains posing as heroes, known as the Dark Avengers.
As we’re very familiar with the Green Goblin by now, it would be great for Marvel to utilize Osborn in a fresh way, which this storyline certainly would. Giving the villains all the power would be an interesting move, too, as it would shake up the usual formula.
