If you look at the script heroes may seem different, but if you see the specifics heroes is completley coppin 4400 for the material. The 4400 was a great show only to be cancelled do to low ratings and the rise of heroes.
Look at the heroes powers healing, precognition, induced craziness, telekinesis, a monster with a whole lot of powers. If you think about it heroes even had the balls to take probably the focal point story line of season four, promicin, a serum that once injected could give anyone power, but came with a risk. I feel that it is not fair for heroes to be stealing ideas and getting all the credit. Dont get me wrong heroes is a good show, but its not fair that 4400 wasnt picked up by a better network when it told a better story.
