In today's overcrowded television world, networks are pulling out all the stops to get viewers' attentions.
From huge movie theater premieres to big star castings and franchise spin-offs, these TV shows debuted with much fanfare but failed to hold up under the spotlight.
Here are the 10 most overhyped TV shows of 2017.

"Girlboss" (Netflix)

Netflix made a really big deal of its new comedy, "Girlboss." The show was based on the real rags-to-riches story of Sophia Amoruso, who made a fortune selling vintage clothing online with her company Nasty Gal. Netflix invited fashion bloggers to LA for a multiple event celebrating women entrepreneurs.
With the wave of protests about the unfair wage differences between men and women being a huge topic and the support behind Hillary Clinton's bid for president, it all should've worked out just as planned. But two things happened to derail the hype.
First, Amoruso filed for bankruptcy in November, which took some of the wind out of the Netflix show's sails. And second, the show was terrible. It ended up being canceled after its first season.
"24: Legacy" (Fox)

Fox tried to keep the details of its new "24" series under wraps, which only created a lot of hype. With a similar "real-time" countdown to Kiefer Sutherland's original hit drama "24,""Legacy" had a lot going for it: all the original producers and many of the stars returned, an already established name and fan base, and a diverse lead in "Straight Outta Compton" star Corey Hawkins. So how did they fudge that up?
The show suffered from a stalled storyline and ratings too low to account for such an expensive production. Fox canceled it in June, though the network still thinks the "24" franchise has some juice in it. We'll have to see if Sutherland will be part of any of that.
"Doubt" (CBS)

Movie actors starring in TV series is one of the most popular ways to get some attention for a show (as you'll see many times in this article), but a controversial star returning to TV is even better.
Katherine Heigl infamously left "Grey's Anatomy" in a storm of controversy after withdrawing herself from Emmys consideration and smack-talking the writing for her role. She would later find herself in more hot water after bad-mouthing the movie she starred in opposite Seth Rogen, "Knocked Up."
This year, there was a lot of attention given to CBS's "Doubt," Heigl's return to TV as a defense attorney at a boutique law firm who begins to fall in love with her wealthy client. Its cast also included the talented actors Laverne Cox and Dule Hill and was created by producers from "Grey's" and "Madam Secretary."
It should have been good, but, whoa, it was not. Viewers never showed up and it was canceled after just two episodes.
