1. That 70's Show That 70's Show without Ashton Kutcher and Topher Grace? I see you there, Josh Meyers, but even being the brother of Seth couldn't save this series. 2. Three's Company You really thought you could do this show without Suzanne Somers by introducing her cousin, Cindy? Please. (The blonde in this photo, however, is actually Nurse Terry.) 3. X-Files David Duchovony left the series midway through season 8 and was replaced by Robert Patrick. Scully needed Mulder. 4. Scrubs Speaking of brothers of famous people, James Franco's baby brother Dave joined the cast of Scrubs when the show switched from NBC to ABC in its final season. It may have featured Eliza Coupe — now of Happy Endings — but even she couldn't replace the many characters we missed. 5. Bewitched When Dick York was replaced by Dick Sargent in the role of Darrin Stephens, people noticed. They weren't happy about it, either. 6. News Radio When Phil Hartman died in 1998, Jon Lovitz came in during the show's 5th season as his replacement. It simply didn't work and the show was cancelled soon after. 7. Law and Order: SVU When Christopher Meloni announced he wouldn't be returning for season 13, all of America cried in unison, "But what about Elliot Stabler?!?!" I haven't really watched this season. Is it as bad as I assume that it is? 8. Roseanne Is that you, Becky? Because all I see is a too-friendly version of what you once were. (Sarah Chalke, ironically, was one of the cast members who left Scrubs in its last season.) And without John Goodman in many episodes towards the end of the show's run it was truly a shell of what Roseanne once was. 9. The Dukes of Hazzard It was before my time, but I hear that replacing Bo and Luke with Coy and Vance was simply awful. 10. Beverly Hills, 90210 Apologies to Noah, Gina, Janet, and Matt but something was seriously lacking without the any members of the Walsh Family residing in Beverly Hills. Sure, Dylan came back for a while and Tiffiani Amber Theissen provided a good replacement for a bit — but only while they lasted, which was not for too long. 11. The Office I hate to kick a show while it's down, but neither James Spader nor Catherine Tate have been able to replace Steve Carell. 12. Happy Days By season 11, Richie and all of his friends had left the show and Scott Baio doesn't quite make up for it as his replacement. They were better suited for their spin-off, Joanie Loves Chachi. 13. Two and a Half Men Can you believe it's already been a year since Charlie Sheen was fired from the show and replaced by Ashton Kutcher? Time flies. 14. Spin City Speaking of shows related to Charlie Sheen, did anybody else stop watching Spin City when Michael J. Fox exited? Sure, they brought on Sheen and Heather Locklear... but the show was never the same for me. 15. Saved By The Bell: The New Class Saved By The Bell without Zack Morris, A.C. Slater, Jessie Spano, Lisa Turtle, and Kelly Kapowski IS NO SAVED BY THE BELL AT ALL.
