I'm still watching the show, but I'm getting impatient. The characters feel too disconnected from each other. They only meet here and there, only to separate a few minutes later. Like with Hiro and Niki's husband and kid last night. I felt like cheering for a half-second, then realized they'd probably go their own way quickly, and that's just what happened. IMO the characters really need to start forming long-term (as in, lasting several episodes at the least) associations.
Oh, and will Claire's rescue (or at least, the events that will lead to her needing rescue) get on the road anytime soon? At this pace, I wouldn't be surprised if it was the frickin' season finale.
This is starting to feel like Lost; lots of hints and teases, an occasional crumb to keep viewers watching, but never a really satisfying payoff. I dumped Lost at the end of the first season because of that - now I'm starting to wonder if I should do the same with Heroes.
