Last fall, the broadcast networks bet that the best way to attract viewers was by programming reboots and revivals of popular series and movies. However, Limitless, Minority Report, The Muppets and Heroes Reborn had limited success at reigniting that spark with audiences. Limitless is a hit for CBS. But Fox's Minority Report and NBC's Heroes Reborn won't be returning for Season 2, and ABC is retooling The Muppets in an attempt to win back viewers who were driven away by its more adult tone. Last August, NBC scrapped its straight-to-series revival of '90s sitcom Coach after shooting just one episode.
