I don't remember the face but the dress is familiar...

It reminded me strongly of Ian McDonald's "Chaga" books: alien life occupying an area of Earth and changing all life that enters. The books, of course, go more deeply and contain much more incident, but the basic ideas are so similar that I find it hard to believe there's no connection. If you haven't read the books, do - they're far better than this.
Apart from that, the idea that the culprit here is "refracting" DNA is a bit daft and, frankly, unnecessary; "changing" would have been enough. It would have been refreshing, too, if the usual assault rifles & military fatigues had been missing but hey, everyone knows that the best way to fix anything you don't understand is to blast the hell out of it. Which of course is why everything was finally solved in good old Hollywood style, with an explosion. God bless America.
