Packed with train wrecks, stagecoach chases, runaway rockets, and more puns than guns, The Adventures of Brisco County, Jr. is a nervy attempt to do something different with the TV Western. Although its winking attitude has already been widely compared to the ’60s oldie The Wild, WIld West, Brisco County is less satire of the Western clichés than a revitalization of them. Bruce Campbell, who managed to keep a straight face in loopy Sam Raimi horror films like The Evil Dead and Army of Darkness plays Brisco County Jr., a Harvard-educated lawyer-turned-rootin’-tootin’ bounty hunter. Executive producer Jeffrey Boam was a writer on genre-spoofing feature films like Indiana Jones and the Last Crusade and Lethal Weapons 2 and 3, and he has put the same knowing spin on Brisco’s adventures in this two-hour premiere are the introduction of a real gas of vicious villan (Billy Drago) and an ongoing, science-fiction sort of goal — Brisco is in search of the Orb, a mysterious object that everyone wants, for reasons not yet clear. As cliffhangers go, Brisco County has itself a doozy. B
