It seems that a struggling NBC drama could be done for after four seasons. Vulture is reporting that Heroes will likely be canceled by NBC, despite the talk of a fifth and final season for the series.
It was said that NBC was looking to wrap up the series with a final 13-episode season to give it proper closure, but with its growing slate of new series pickups even before their upfront presentation, it was believed the show will be no more, due to NBC's confidence in their new pickups. However, the site is also reporting that the network is willing to give the series some closure by ordering a TV movie to wrap up the show. Here's an excerpt from the article.
However, NBC (which declined to comment for this story) is nothing if not appreciative of the few Heroes fans who still care about the saga and doesn't want to leave them hanging. While a half-season appears to be out of the question, we hear there's a good chance the network will at least try to find a way to fund a two- or four-hour movie event in order to give some finality to the franchise. Those discussions haven't taken place yet, however, since NBC still hasn't officially told Heroes creator Tim Kring his show is canceled. Networks like to hold on to as many cards as possible headed into their annual upfront announcements (NBC's is on Monday), in case some last-minute development suddenly shifts the scheduling equation.
