This offering feels like a lesser work compared to American Graffiti. "Happy Days" appeared shortly after that well-regarded film about teenagers growing up in the late fifties and early sixties. While "American Graffiti" possessed some appeal, this show seemed primarily concerned with negativity. The portrayal of delinquents started right away, and regardless of what those connected with the program might say, “Fonzie” was clearly intended to be the central figure from the beginning—the initial season demonstrates that. Essentially, the series served as a way to portray young men who didn't fit in during the seventies because of their appearance, and that reflects a broader reality about the United States in that decade. There’s simply nothing else of value here; it attempts to be humorous but comes across as an example of animosity and bias.
