Harry and the Hendersons
We don't know which is harder to believe, that a family found a Sasquatch during a camping trip and decided to keep it as a pet or that this incredibly stupid premise could somehow sustain 72 episodes of a television show.





My Big Fat Greek Life
When My Big Fat Greek Wedding pulled in a mind-melting $241 million, you'd think the producers would quit while they were ahead. Instead, they pushed their luck with this horrible show that lasted all of seven episodes on CBS in 2003. Hopefully they learned a valuable lesson: Greek people are only funny on big screens.





Planet of the Apes
What do you do when your first attempt at a TV adaptation gets yanked after 14 episodes? Call up some animators! That's the logic that gave us 1975's Return to the Planet of the Apes, the Saturday morning cartoon featuring the apes in a technologically advanced society where they drove cars and watched movies. And this didn't succeed why?!






Ferris Bueller
With a solid lead in, a young Jennifer Aniston as Jeannie, and an edgy, shortened title, you'd think this 1990 sitcom would've been a slam dunk. Instead, it's remembered as the show that was replaced by Blossom.






Uncle Buck
Kevin Meaney is no John Candy, and, sadly, the world had to learn this the hard way. Considering this 1990 show had everything the original movie did—well, replace the fun-loving "parents on vacation" subplot with the hilarious "parents dead in a horrific car accident" subplot—it's amazing it didn't catch on.
