'Sliders'

"Sliders" should have been a widespread hit, but it was ahead of its time. The show was about a whiz-kid genius Quinn Mallory, played by Jerry O'Connell (left), and his band of three companions who slide among Earth's alternate realities. Toward the end of the series, the show quickly slid in quality as three of its stars - O'Connell, Sabrina Lloyd and John Rhys-Davies (right) - departed and were replaced by others. A tragic demise to a fine show.
