It was, as many things are in Hollywood, a little self-serving but the broadside against reality TV in “The Practise” Monday night was also good television. Who knew that a media diatribe could be made so deftly or that webheads had such a sense of fun!In the episode a deranged woman takes Leslie Moonves hostage in order to compel CBS to pick up a reality show about the kidnapping and the possible execution of the Eye topper. Both Fox and NBC come into play as bidders for the show. The episode allowed “Practise” producer David E. Kelley to take pot shots at the reality genre, the increasingly shameless variants thereof and the seemingly limitless prurience of auds that watch this stuff. ABC recently switched Kelley’s show from its Sunday berth to Monday nights, where it was dealt a blow by Fox’s “Joe Millionaire.” Monday’s episode was topped among adults 18-49 by Fox’s “Married by America” — a clear sign that good drama is suffering at the hands of these tasteless hybrids. Let’s hope this is the first salvo in a campaign to shame webheads into pulling back from the worst examples of this genre. Or will someone really have to die on camera first?
