Heroes is an interesting show. I'm still not totally caught up. I think I'm at episode 14 or so. And there have been something like 18 episodes so far.
Heroes takes longer to watch partly because the show is 1 hour in length (versus Entourage's light 30 minutes), and partly because it is more complicated and I can't seem to watch too many episodes in a row without getting tired.
It seems Hiro Nakamura is emerging as the fan favorite. He certainly is one of mine, mostly because he has such a positive outlook on life and provides a lot of the comic relief of the show. And this is a show that sometimes needs relief.
But all of the characters are starting to grow on me a bit. Looking forward to getting completely caught up.
