Cultural critics never fail to insist that this is the worst that it's ever gotten, that the media have never been more sensationalistic or depraved; right now, there are plenty of people who will tell you that TV shows such as Here Comes Honey Boo Boo or Jersey Shore represent a heretofore unimaginable cultural nadir. But the morally outraged tend to have a short memory, which is why they don't remember mid-1992, when the nation was entranced by the media coverage of Amy Fisher, a 17-year-old who shot her 36-year-old lover's wife in the head. How entranced were we by this story? Seven months later, ABC, CBS, and NBC each broadcast a made-for-TV Amy Fisher movie within the span of a week, and the versions starring a slumming Drew Barrymore and Alyssa Milano went head-to-head on the same night in a statutory rape-'n'-ratings showdown. But director Dan Kapelovitz has not forgotten those dumb days, and his fascinating Triple Fisher: The Lethal Loliltas of Long Island (playing tonight at the Roxie) is a mash-up of the three pictures, resulting in a Rashomon-like retelling of a story which didn't really need to be told in the first place. Kapelovitz's audacious video remix of the worst of the '90s even makes it worth hearing the word "Buttafuoco" again.
