Doom could have better. They gratuitously changed the plot, which is funny because Doom has practically zero plot at all. And they managed to change it without improving it in the slightest—for the purposes of the movie, they could have easily gone with the "opened a portal to hell" and the rest of the movie would have been the same. Their changes were really dumb and completely pointless which was really frustrating. Also the first person part at the end was unnecessary and just wasn't good cinema (compare to Hard Core Henry which was 1st person but it worked because they really committed to it).
