Doom 2016 would have actually been a very good framework for a no holds barred, excuse-plot-followed-by-nothing-but-protagonist-killing-stuff, John Wick style action movie, but since the game exists, a movie would be really redundant.
But… if I had to do a Doom movie that was more than that, I'd resurrect the original game's lore and tell the story of a good-hearted Marine, stationed on Mars for beating the shit out of his CO after said CO told him to fire on civilians. Then the portal to hell gets opened, his bunny gets killed, and he's just like "nah, this isn't some kind of failure to communicate or bad first impression. If these demons killed this innocent little bunny, then they're just straight evil." Then he starts killing demons with ever-increasing efficiency and speed, fights his way through hell, has a big climactic battle with the Icon of Sin, wins, and goes back to earth as a war hero. And some people talk shit about him being a monster and stuff but fuck them, he just retires and makes himself a quiet family life.
ALTERNATIVELY, after the Icon of Sin dies, he gets a salute from the spirits of long-dead crusaders and demon hunters, then just stays in hell and keeps killing demons until he gets locked up, bridging the gap between Doom and Doom 2016.
Also, this movie should NOT go for one-liners, Doomguy starts pretty normal, but talks less and less as the movie goes on. If we ever cut away to the demons reporting on his rampage through hell, at some point someone should probably say something along the lines of "the sounds of gunfire… the screams of dying demons… those are his voice". Would depend on how much if at all the demons actually talk. If Doomguy does get a one-liner, make it something about the bunny right before he kills the Icon.
I don't watch movies very much though so my ideas are probably shit.
