The Battery already has a fair amount of people advocating it as a great micro budget horror drama. Despite looking and acting like a lot of other indie films, you can easily see why it might raise some enthusiasm. Writer and director Jeremy Gardner underplays the catchy zombie angle just enough to make the meaty relationship at the film's core feel meaningful and sincere. But he doesn't ignore the zombies, either. Old Joy fans who roll their eyes at zombie films and horror fans who roll their eyes at Old Joy both get to leave the theater in perfect entertainment harmony.
