I think that the film version of Doom should take inspiration from real life revolutionaries like Vladimir Lenin and Che Guevara. Not to say that Doom should share their ideology (although I could see Doom believing in a very dark and ruthless interpretation of socialism, but that can open an ideological can of worms that maybe this franchise shouldn't get into), just in their methods and their public persona. Doom should feel like someone who people would actually willingly follow in a glorious revolution against a brutal dictator. I also think Doom should mirror the complex morality of those men. While ultimately, yes, Doom is a villain and does terrible things, often for petty reasons, I feel like Doom should be portrayed as a man of great vision and conviction who truly wants what's best for Latveria and the world, but is burdened by a great darkness that gives him a strong tendency to carry out his plans with a savage ruthlessness and makes him unable to let go of old rivalries and petty hatreds.
One thing I think is important is that they portray his petty jealousy of Reed Richards with some subtlety. I don't think it should be something that's kept him awake at night for the last ten years. I think that after he left ESU, he went about his long journey towards rallying his army and overthrowing Latveria's government, and didn't think about Reed Richards at all during that time. He wanted revenge against the King for murdering his father and he wanted freedom for his people, and that's what occupied his thoughts. Then, years later, when Doom is the ruler of Latveria and has been for a little while, the Fantastic Four becomes a thing and Doom sees them, and his old friend and rival's intellect, as a resource to be acquired for the good of Latveria. But, as he goes after them for entirely practical purposes, all of that pent of jealousy and resentment towards his former friend begins to bubble up to the surface and color his actions and intentions, and as Reed and the FF regularly thwart him all of that jealousy and all of the anger he's been carrying inside of him his whole life that no longer has an outlet all gets focused on Reed and his family, and their rivalry becomes entirely personal.
Also, an idea that I had that I rather like is that, when Doom and his army takes Latveria, he doesn't set up a dictatorship. He sets up an entirely democratic constitutional monarchy. There's a Parliament and a Prime Minister and regular free and fair elections and political parties and everything. Doom becomes the King of Latveria as a figurehead position, much like the monarch of the United Kingdom, and all of his constitutional powers and duties are chiefly ceremonial in nature. He says to his followers from the revolution that it was his duty to tear down the old order, and it is now the duty of the people to build a new one, and his role now is to serve as a guide and counsel in more of an emeritus position.
However, even though Latveria is a democracy and all of the real constitutional power lies with the Parliament and the Prime Minister's cabinet, Doom is engaging in so much behind-the-scenes manipulation, gathering intel on everyone and making shady closed door deals and using blackmail and bribery and whatnot, that he's basically the one running the country regardless of what the law says. In his mind, Latveria is a free democracy rules by the people and he isn't a dictator, he's simply taking some necessary measures to insure Latveria's security and future growth through means that run parallel to the legal and political process and use his influence in an appropriate manner, and he absolutely does not see the cognitive dissonance there.
What surprises me is anyone who likes Doom who would want to see anything that radical done to him when we've already had enough character assassinations with this movie franchise including the past Dooms of Fox's failed attempts. Guess at the end of the day, Corman's F4 is still the most faithful in both look and character adapting.
It's because changes aren't bad. It's
bad changes that are bad. Movie studios don't have an upper limit to how many changes from a source material they get to make, and if they use them up on bad changes then they don't get anymore. That's kind of silly.
So is the idea of a female Doom...are you even a fan of the character? How could you even remotely want to see that done to him? Doom is one of the most iconic characters in all of comicdom...to have anything short of his comic book look, attitude, agenda, goals, etc. is giving the character the shaft.
No it isn't.
That wouldn't only be the case if changing the character's gender would in any way diminish the character.
That being said, I'm not sure I trust Hollywood to keep the nature of Reed and Doom's rivalry 100% platonic if they changed either character's gender, so I'm not sure it's a good idea.
