Bwah! I adore the My Two Dads thing so much. It almost makes up for Mohinder being a box of hair (and how!). But at least he's consistent!
I love Hiro and enjoy Japanese adventure stories, which is what Hiro is guiding Kensei through.
{insert boilerplate furious-at-white-Kensei text here} Because otherwise I would enjoy the story. But I don't.
That said!
I am enjoying the Generations aspects of this season very much. It's kind of analogous to growing up in general. At puberty, discovering all these weird new attributes about yourself and about life in general. Thinking it's all about you and it's crazy and scary. Then finding out that your friends are going through it too, and bonding over the fear and excitement. It's not until later that you slowly get an understanding that your parents are people too and they went through all this before you. And, you know, maybe you should talk to them about it. Right now the two (three?) sets of heroes are so independent, but I think they will need each other more and more.
I also like the idea of seeing the repetition of powers, and powers amplified and expanded, like the parental relationship with Matt. Seeing limitations of powers, and what that means to vulnerability.
Although the generational power amplification thing doesn't seem to apply to the youngest generation of heroes. Flying & Fire = Healing? Walking through walls & Superstrength = Mechanical manipulation? We still don't know Hiro's dad's power, do we?
