10 More Horror Films That Tried Something Different (And Failed)

One of the most important aspects when it comes to adapting a video game is understanding the source material. Now, a lot of video games have messy storylines that are difficult to condense into a two-hour flick. However, Doom shouldn't have that problem since the plot couldn't be more straightforward, as id Software's influential shooter centres around a marine who battles demons. That's it.

So, what did the 2005 film adaptation do? It got rid of the demons. 

Rather than facing off against the forces of Hell, our hero must contend with infected humans. Though each game concludes with the marine battling a gargantuan monstrosity, the movie's big bad is a zombified soldier played by Dwayne Johnson. Granted, the Rock looks intimidating, but not so much when compared to classic Doom foes like the Cyberdemon or the Icon of Sin.

Though most of the infected resemble their video game counterparts, it's bewildering why the writers thought the fanbase would be onboard with this pointless departure. To the movie's credit, it went above and beyond to create a first-person shooting style for the third act. But apart from that, nothing else about this dumpster fire captured the spirit of Doom.
