 The first half aired, ending with a Melmacian spaceship hovering over ALF, while Alien Task Force operatives were closing in from all sides.But despite the flash of "TO BE CONTINUED", the network never allowed any more episodes and left fans furious with that decision, leaving the series on a cliffhanger for over 5 years.Actors William O'Leary and Jensen Daggett were already working together on ABC, playing husband and wife Marty and Nancy Taylor, brother and sister-in-law to Tim "The Tool-Man" Taylor on the top-rated sitcom "Home Improvement".
