I recently discovered (while conducting research for an article, actually) that Home Improvement is not available to stream on any major platforms at the moment.
However, star Tim Allen has actually expressed interest in a reunion show, which not only sounds like a fun idea, but would also answer the question of what the rest of the cast has been up to lately.
The highly rated comedy ran for eight seasons throughout the 1990s, made a huge star out of Tim Allen (who also earned a Golden Globe for his lead role in 1995), and jump-started a few other notable careers.
Created by Carmen Finestra, David McFadzean, and Matt Williams, Home Improvement follows a home renovation TV show host who finds that dealing with common household repairs is often easier than handling family issues (despite experiencing a mishap or two with both).
