Regarding the optimal duration, there's an unwritten rule in the media industry that a full-length entertainment show should last 2-3 hours. This range includes movies and sports matches.

Road cycling races last 5+ hours, the most famous ones have been held for over 100 years, and they attract a TV audience comparable to the World Cup final. At the same time, no one thinks of forcing the unforceable into a media standard; everyone understands that it's just a type of sport. And Heroes is simply that kind of game.
