They, with the possible exception of Noah to some degree, were not really built for in depth characterization or to last over seasons.
I would also add that Mohinder, before he went all Seth Brundle/mad scientist like, had the potential to ladt a few seasons. He had a more sympathetic, yet limted, understanding of what the supers were going through. He could have been just as good, if not better, character than HRG.

Anyway, it seems like they're going somewhere with it, so I'm willing to wait it out.
