Well, if you are in this movie for zombies, don't get your hopes as, as there aren't actually any 'stereotypical' zombies as in shambling, ravenous flesh-eating ghouls. However, the movie does have a strange infection that causes people to become feral and rapid, doing bodily harm and injury to others, much alike zombie behavior, yes. But not zombies as in the usual type that we are used to.
That being said, then I am not saying that "Dead Air" is a boring or not worth watching, because it is actually rather enjoyable. The storyline is good, fluid and fast paced, although the ending to the movie was rather cliché and predictable.
What makes the movie work so nice is the dialog, because there is a lot of clever banter throughout the movie, and Bill Moseley really nailed the role of a radio host quite well, and I was pleasantly impressed. I enjoy most of his movies, but he really pulled off this role quite amazingly well. And it was also great to have Bill Moseley and Patricia Tallman together again on the screen, although in very different roles from their last collaboration.
As much of a zombie aficionado that I am, then I enjoyed this movie for what it was, a sort of early-stage infection movie that could have lead to the zombie outbreaks that we are accustomed to seeing in the movies. The story was well executed, and it did bring up some rather interesting points about how mankind create things often used for destruction, as well as the destructive nature of mankind. Whether or not you pick up on these viewpoints (or even care about them), then "Dead Air" is good entertainment from start to end.
And amongst the callers who call Logan's show, there are some nice treats; they had some fairly great names adding their voices to the show, which was a subtle, but rather nice touch.
"Dead Air" is definitely worth watching for fans of Bill Moseley and for fans of a proper good suspense movie in overall.
