Because we don't get nearly enough of those, right? If anything, this movie is quite disjointed. For instance, there is the character of the apartment building manager, who is this effete intellectual philosopher who seems to have no place running a seedy, inner city hotel. I say this, because it is obvious this trash was produced by Europeans, and this is probably how they see America.
The long and short is that the Army has acquired an alien virus, and tested it on people, turning hundreds into Zombies in Iraq before a smart bomb blew them all up. Then a Captain in the research project returns to the states and starts all over again, because, hey, it worked out so well the first time. He injects the virus into a gangbanger, and a junkie self-medicates with the rest, until the entire building is overrun with zombies.
I think there is supposed to be something about the aliens wanting to communicate... Not sure, I think it was lost in all the gore.
