I saw the first episode of Heroes when it was first televised here in Australia, and I thought it was quite cool, but I missed the remainder of them. And then I got access to all of the first season (or at least the first 15-odd episodes), and sat down and started watching.
I love it.
This is a program that really shines when you sit down and watch it in a big block. I would, I’m sure, be very frustrated if I had to wait a full week after the TO BE CONTINUED… that ends each episode. But being able to follow the characters immediately makes it a very enjoyable experience.
