To be honest, when i first started watching heroes i was expecting it to be quite action-centered. This isn't the case, however, i was drawn in by the sheer human-ness these characters portray.
Heroes poses an interesting question: what would the everyday population do if they discovered they have superpowers?
Most wouldn't put on spandex and fight crime under a secret identity - some would be scared, and hide their ability from others. Some would be excited, and embark on an adventure to try to save the world. Some would think this ability made them better and more important than the average man and would react accordingly...
Heroes is a rollercoaster ride filled with mystery. There's enough action involved in it (granted, quite a few episodes into the series) to quench most people's thirst, and there must be at least one character you can relate to:
Hiro, a japanese office worker who dreams of being a hero.
Peter, a NY nurse who feels he was meant for something more important.
Niki, a single mom who is struggling to provide for her son.
Claire, a texas cheerleader who thinks her father may not be the person she thought him to be.
Matt, a cop who has been directing traffic for a number of years, and who has problems with his wife at home.
In short, if you don't like heroes, seek professional help.
