I did notice that... lol... I'm not really into those kinds of movies, and only watched Doom because my husband and brother were watching it...
I thought it was pretty bad. Then again I prefer movies like Jak X (www.jakxdvd.com you should check it out its one of the best video game movies out there) and movies like Advent Children because they are truer to the actual video games.
Doom was probably the worst movie of all time, right in the same category Starship Troopers 2 and Battlefeild Earth IMO. However the games are still some of my favs of all time.
