A post-Vietnam, mid-Afghanistan allegory about the wages of imperialistic sin, "Dances with Genetics" entertains, yet leaves you hungry an hour later. Our fearless protagonist, ex-Marine Jake, faces a terrible choice: fulfill his mission as a secret agent and destroy the adorable aliens or spend eternity in sequel-land, cavorting with the universe's sexiest gymnast. Semper fi, dude! Despite its excessive recapitulation of "Ironman", the film also bows to the original "Alien", with hi-tech sleeping pods, aliens threatening the mission, and Sigourney Weaver in white undies. Given that the visuals are what make the film, this is a 3D IMAX-ONLY mega-meal of hi-tech fast-food. But don't sit too close; genetic transmutation is a risk.
