Spinoffs can be hit or miss. While some become more popular than the original show that inspired them, most end up being low-rated and utterly forgotten. But other times, there are great ideas for spinoffs that simply won't work because of time constraints, lack of money, or lack of interest. Here are some great ideas for TV spinoff series that are unlikely to happen.
"Better Call Saul": A "Breaking Bad" spinoff
There's been a lot of chatter about the possibility of a spinoff series for Saul Goodman, the sleazy lawyer on "Breaking Bad." Bob Odenkirk, who plays Saul, has some ideas about how the series might go down.
"Saul could become the mayor of Las Vegas," Odenkirk said. "He could become the most respectable citizen in the city. Or he could go to L.A., because he's flashy and he likes being in the spotlight, and you know, L.A. lawyers can get in the spotlight."
Why it will never happen: While Vince Gilligan, the show's creator, is open to the idea of a spinoff, it's more likely he will move on to an entirely new project. After a show like "Breaking Bad," a spinoff would seem weak by comparison. The rumors have been floating around for years at this point, but there's no concrete evidence this concept will take off. If this series was really in development, the press would have picked up on it by now.
"Hannah": A "Dexter" spinoff
No one is sure how the final season of "Dexter" will play out, but many fans are hoping that Hannah McKay will return at some point. "Dexter" is Showtime's keystone series, and it makes sense that the network might consider greenlighting a "Dexter" spinoff to help keep Dex's fans around. How cool would it be to see Hannah McKay traveling the country, acting as a "poisoner-for-hire" and killing bad guys?
Why it will never happen: Dexter Morgan has a habit of killing his enemies. Given how Hannah and Dexter left things after Deb's near-death experience, it's likely that if Hannah returns, she will end up on Dexter's table.
"Bates and Bates, Private Detectives": A "Downton Abbey" spinoff
Anna might be happy as a lady's maid, but she also clearly yearning for something more. She's already proven that she's good at solving mysteries and was responsible for securing her husband's release from prison. Anna and John Bates are the fan-favorite couple on the show: If there's a "Downton" spinoff, it should center around them. Why not give the fans "Bates and Bates, Private Detectives," and watch Anna and John solve crimes in pre-War London?
Why it will never happen: If a "Downton" spinoff gets the greenlight, it's more likely to be a prequel series. Insiders say that a spinoff would likely focus on the time around Cora and Robert's courtship, when all kinds of American socialites were traveling to England to find a titled husband.
