Heroes begins its new season with a two-hour premiere tonight (NBC, 8 pm ET/PT), and although the series has suffered through plenty of criticism by TV journalists (and the average fanboy), the show is trying to win back its initial praise by going back to basics.  Milo Ventimiglia, who plays the anxiety ridden hero Peter, talks about some of the changes that Peter will experience this season.  (CLICK ON THE MEDIA FILE)
