10 TV Shows That Suffered A Sophomore Slump

10. Heroes

The first season of Heroes had its issues but was generally well-liked and seemed to have bags of promise. There was a little period where you couldn't get through a single day without hearing someone quote the show's famous tagline: "Save the cheerleader, save the world". Unfortunately, the second season was a major disappointment.

The 2007-08 writers' strike affected the production of season two of Heroes, resulting in just 11 episodes being produced compared to the original planned tally of 24. With less episodes, you might think that the show would be faster-paced and more action-oriented, right? Wrong.

Instead of a thrilling, superhero comic-style story brought to life on the small screen, viewers were forced to endure painfully slow episodes and the introduction of a whole host of new characters on top of what was already a large cast.

Sylar (Zachary Quinto) was regarded as one of the best baddies on TV, but season two's terrible changes proved to be the ultimate villain for Heroes; Peter Petrelli and friends did survive for a third and fourth season, but ratings rapidly declined and the show was eventually cancelled.
