Yeah, they've dropped, but not enough to be canceled. I've seen the ratings comparing now to season 1, significant difference yes, but I"m willing to bet money they have at least two seasons more. And you're right, they tests ratings more than just by regular ratings now, they're trying to track TiVo and DVRs, internet views, international, so like I said they have at least two more seasons. I'd rather the 4400 anyway me personally, I need a sci-fi fix even if it's subpar, might start catching battlestar gallactica from season 1
The 4400 did something Heroes should of done; have a bigger picture.
Kind of like Lost with the Island. The 4400 had the whole future was in danger and had a lot of mysterious characters. I kind of see the 4400 as a Heroes season 1 stretched out.
But I knew Heroes was going to drop the minute season 1 ended. Its too difficult to have a consistent serial drama that involves super powered humans. Especially since you'll be closely watched on how creative you get without dipping into the *cough* x-men/superman/comic genre pool. *cough*
IMO, they should end it at 5. Work hard on season 4 to get the ratings up and end it with a bang.
Lost was originally planned for 5 seasons and Supernatural is done after 5 seasons. To me, those are 2 of the best shows out right now.
