To join this trend of post-apocalyptic films with zombies, Extinction a film that is based on the novel by Juan de Dios Garduno titled Y Pese a Todo..., loosely translated in English as And Despite Everything, which incorporated the elements of nature, horror, and a little drama. However, I found the film to be lacking in character development and world building.
The film begins with a brief introduction of the main characters and the reason for their isolation nine years later. However, it was lacking in describing how the world got to its current state. Yes, we got rabid and vicious people attacking/infecting others, but this "ice age"?!? Where's the explanation to that? The few flashbacks that were incorporated into the film did further explain..a bit... regarding the relationship among the three... Patrick, Jack and Lu. The realism of the characters and their relationships just didn't come through for me. The acting just seemed stiff...
It is apparent that after nine years the infected adapted to their cold environment. The film has the familiar theme with 28 Days Later film. When survivors adapted to their cold environment, so did the infected... and how they adapted turned out to be hideous and horrific. The element of horror was definitely present with the "jump in your face" scary... very few, but it was there.
All in all, it was a somewhat enjoyable film that intertwined horror and drama. There was just enough of these elements to tie together the storyline.
