Most unnecessary spinoff

“Heroes Reborn”

When “Heroes” premiered in 2006, it introduced a captivating mix of mostly unknown actors playing ordinary people who discovered that they had superpowers. The special effects were extremely cool, especially when high school cheerleader Claire Bennet (Hayden Panettiere) could spontaneously repair her body after falling off buildings and getting burned. Both critics and audiences loved the show — some 14 million viewers watched the premiere — and it received eight Emmy nominations in its first season. But the quality of the show started to deteriorate as early as Season 2, and the slowly declining numbers proved it. The Season 4 premiere only attracted 5.9 million viewers. America didn’t need any more TV “Heroes,” which raises the nagging question: Why did NBC decide to do it all over again? Rather than NBC giving us a new idea for a series, they’ve gone into the TV graveyard.

Premiere: Sept. 24, 8 p.m., NBC
