After entering a hiatus, the series continued without Ritter, incorporating the death of his character.James Garner and David Spade joined the cast afterward.
The three new episodes that Ritter completed were aired with Sagal introducing them.
The show returned two months after Ritter's death, with a one-hour episode, "Goodbye", which was turned into a tribute to Ritter's character.
ABC canceled the series on May 17, 2005 after three seasons due to low ratings.

The third season (after Ritter's death) took a creative turn, revolving more around cousin C. (David Spade) and grandfather Jim (James Garner), than the immediate Hennessy family, more specifically not revolving around the raising of the Hennessy girls.
After the novelty of newly added ensemble characters wore off, the show shortly returned to its roots.
