In one respect, the film (and book) represents a fresh variation of the post-apocalyptic genre that's saturated the industry over the past decade or so. However, the dreadfully lethargic flow of the plot, predictable/cliche characters, costumes more reminescent of 1970s sci-fi flicks than futuristic, and the force-fed (but not quite lusty) infusion of troubled teen/puppy love dilemma overshadow the survival aspects of the plot so thoroughly that much is left to be wanted. In my humble opinion, at least 20-30 minutes of the first hour of the film could (should) have easily and beneficially been left on the cutting-room floor. Other gripes: The CGI killer dogs were among the most unrealistic "digital dogs" I've seen in post-2000 films. Lastly, the film was peppered with so many cliche, normalized, and stereotypical character shells, circumstances, and conflicts/solutions that the film squanders any opportunity to create a lasting or profound impression on the film-goer; and while that does not likely negatively impact the film's profit-generating potential in a substantial manner, it does contribute to the film's eventual relegation into the ho-hum (yawn...) category of the post-apocalyptic genre that seems to be the default background setting of contemporary epics.
