Good, but could use a bit of polish.
Graphics were competent, but weren't animated, and could stand to be a little cleaner. But, this being Newgrounds I should give you a totally heterosexual hug for NOT using stick figures as your primary character models.
Style was good however, and the rendering of John Romero was spot on, with his rock start hair and whatnot. The addition of actual Doom sprites for random background details worked better than it should have any right to.
Sound could use some work. The voice acting was somewhere between good and not so good. For as compressed as the audio was, I'm confused as to why the file size was so big. With the same quality sound and animation this could have been a 3mb movie.
In the violence department, being that its doom, you'd expect to see some dead demons every now and then. And yes, I did see some dead demons in this movie. Well, some dead everything was to be had. Like multiple dead John Carmacks. At least now I know the dangers of ingesting Diet Pepsi.
Though the pacing was slow for my tastes, there were some good jokes in this movie. Specifically the kill cam replay of Romero shooting the professor. Though some of the humor was canned, I did laugh a few times, which for someone as bitter and angry as me is very rare.
Overall, it ran slow, got boring in the middle, but had some good ideas that should be exploited in the next episode.
