Ain't It Cool News has their own DOOM movie panel report, which like GameCloud's report yesterday is mostly positive. The article also features a better description of the movie's first person sequence (which apparently lasts for about six minutes).

I love FPS (First Person Shooters) games and that love started with DOOM and Wolfenstein back in the day. So, it stands to reason that I loved the clip that followed because it was all done as a live action first person shooter. The sounds, the score (temp, natch), the lighting and the sets were all straight out of the game. From the second he walks out the door, you hear the creatures and zombies. He comes upon the zombies first, taking them out with shots to the chest, then head. The gun is lower right screen the whole time. After a zombie or creature is shot, the gun ducks below frame and the reloading sound happens. The camera movement, the strife moves... all looks great... a real live action video game sequence. It's pretty specific in the details... like the zombies are fairly easy to kill, while the Imps take a few more shots to kill and the big clawed fuckers take a lot of ammo... matter of fact, in the video, the first time we see one of these guys he gets about 5 seconds of ammo pumped into him before the gun tilts over and shoots the explosive tank next to it covering the demon in flames. The demon claws at itself as if trying to tear at the flames.
