DVD: Heroes: Season 4, For retail & rental (Universal)

When Heroes first appeared, it was a fresh concept – ordinary people discover their superhuman side.

Then it became an inevitable battle between good and evil. By season four, the plot has played out to such an extent that a carnival is introduced (where these "freaks" can go to feel normal) to get it moving again. Sadly, it's populated by largely uninteresting characters – and it's not hard to see why the show was cancelled.
