Yeah I agree the ending was little soft. I was hopping more of the "heroes" would get involved in the final fight with Sylar than just 4 (and Parkman didn't really count) and maybe he could have killed a few in the process.
And why did Peter need Nathan to fly him away? Couldn't he have just done that himself?
This heroes origins thing could be interesting. I wonder if Hiro makes some medieval babies who go on to become his ancestors thus passing his power on down to himself in some sort of Incestuous infinite loop.
