I love to science-geek about Heroes — and I love company, so these two posts make me happy.
First: Dan Wright at the Den of Geek! writes about some of the genetics questions raised by Heroes — but more importantly, asks will it be a more enjoyable journey than watching Lost? Scathing and funny.
Considerably smarter, two Livejournal users called hagar_972 and nurint got their geek on to develop The Nurit-Hagar Wave Theory, which explains all the superpowers on Heroes as variations on telekinesis and the ability to manipulate electromagnetic fields.
