Comic books CAN translate to movies -- literally, if need be -- if you've got enough creativity, passion and vision.
I give you "Sin City" as the example. Granted, it's the exception to the rule... but nonetheless it's there.
I don't think anyone expects (or maybe even wants) a scene-for-scene reconstruction of FF 5, Annual 2, 39-40, 57-60, 84-87, 196-200, 236, 258-260 etc.... but it can be done.
While this is the "Fantastic Four" and not 'Doom," I'm disappointed that FOX can't give Doom a little bit more thought (and respect for the source material) than they appear to have.
The movies were called "X-Men" and "X2" and not "Magneto," but Magneto had plenty of screen time and the character was pretty faithful to the source material. They said, "well... what do we know about Magneto? LET'S CHECK THE SOURCE MATERIAL, FOLKS! Charismatic old guy with white hair, check. Long history with Prof. X, check. Powerful mutant -- master of magnetism, check. Dresses in red and purple and has a Spartan-soldieresque helmet, check. Leader not a follower, check. Motivations stem from racial persecution as a child, check." They didn't make him a (lowly) human, or part tentacle monster, or a 16-year-old, or a woman, or a subterranean hermit with bug eyes, or a cyborg. And his motivations certainly didn't come from being a jilted lover of Jean Grey.
