Despite these commitments to realism Dog Day Afternoon manages to touch on many of the pressing social issues of 1970's America. In fact, it is because of this commitment to realism that the film achieves such a deeply insightful portrait of that time in our history. The characters' lives are faithful manifestations of a society challenged by Vietnam, myriad misuses and abuses of authority, women's lib, and gay rights - to name a few. I never felt as if I was being preached to. No one issue was singled out as the source of conflict.
In my opinion, when it comes to storytelling, the "ends" cannot justify the "means." It just doesn't work that way. The "means" are EVERYTHING. In this respect, Dog Day Afternoon is cinematic storytelling at its best.
