'Heroes' creator apologises for second series

The creator of hit TV show 'Heroes' has issued a humbled apology to fans for a disappointing start to the second series.

The superhero show, starring Hayden Panettiere and Masi Oka, was the top-rated new drama in the US last year.

But audience figures have taken a dip - with one recent episode placed 30th in the overall ratings.

Creator Tim Kring admits his choice of storylines were a mistake.

He told magazine Entertainment Weekly: "We assumed the audience wanted season one - a build up of intrigue about these characters and the discovery of their powers. They wanted adrenaline.

"We made a mistake - we took too long to get to the big-picture story."

Referring to the recent romantic plotlines, he added: "In retrospect, I don't think romance is a natural fit for us."
