We started watching Heroes last night. I think we saw a bit of an episode a while back and we thought we might like it. So we've started. We watched the 73-minute 1st episode and episode 2. It has some things that we'll probably find a bit irritating, like the "handsome Indian professor", the"intelligent rich black woman" and the "cute kid". But there is enough humour, with the Hiro character, to keep me hooked.
Scary - there is a Heroes Wiki, with all you ever wanted to know about Heroes.
And there is also an associated graphic novel available on the NBC website. It's currently at episode 135. We've got a bit of catching up to do!
