The Cheerleader's Adoptive Dad is truly an interesting character. In the first episodes, it was hard to tell if he was a good guy or bad - and now I'm finally leaning toward good guy in a bad situation, one who really loves his daughter.
He works with that guy with powers to erase as much or all of a persons memories as he wishes, literally even changing the person's personality. The father does bad things (like forcing heroin into a recovering junkie) because the junkie paints images of the future.
The Father mentioned he has been tracking the BAD GUY who is killing off the Heroes for about a decade, so obviously there were many more Heroes and many more to come - it is this theme that reminds me of The 4400, where each week they introduce a new character also with special powers, but typically for only one episode.
I too am interested to see what the Father will do next - I know he is capable of terrible things with little regrets. I think this show has lots of possibilities, having characters with special, albeit flawed special powers is interesting. Hiro can stop time to correct a bad situation, but he has little accuracy when warping thru time. The younger brother of a political candidate who can fly at will only has special powers when near other people with special powers.
I thought it interesting that in a resent episode the Cheerleader was not only dead (to those who don't know it, she has killed herself many times just to come back to life within seconds and with near instantaneous full healing) but she was laying on a autopsy table with her chest-plate removed - when she came to, she reached over, put in back in place and it healed over in seconds. Mean while, the theme SAVE THE CHEERLEADER, SAVE THE WORLD finally makes some sense when we find out that the BAD GUY uses his finger like a laser to cut the top of Heroes heads off, this is the only way OBVIOUSLY to kill the Cheerleader.
It should be interesting, I was greatly disappointed when NBC cancelled SURFACE after the first season, that was really building up after some seriously unrealistic plot flaws. I didn't see it NOT coming back and NBC has been inundated with fan mail asking them to rethink their cancellation.
