Call me cynical, but did Nik Wallenda’s tightrope walk over Niagara Falls really warrant 3 hours of TV coverage? Wallenda needed the underwriting to pay for his long-dreamed-of stunt, and ABC needed some cheap programming, I guess. But three hours for … what was it … about a 15-minute stroll? And the guy wore a safety harness, so where was the drama? Not that I would have wished an accident to happen. ABC had already thoroughly sickened me by repeatedly playing the tape of Wallenda’s great grandfather Karl falling to his death. TV is such a wasteland these days!
