I'm rather scared.
Tim Kring knows he laid an egg with season 2, but seems poised to make the same mistakes. He's said he'll stick to his original plan of introducing a bunch of new characters every season, but that only made sense when his original plan was ALSO to dump everyone from the previous season and make each one self-contained. That couldn't happen after Season 1 became a hit and its characters became popular.
It's time to stop that, Tim. Hold back on new characters. The show is different than what you planned. Now it's become just forcing new guys into storylines whether they work or not. And oftentimes in season 2, they didn't work. The show has become too crowded under this gimmick and it became difficult to follow one story in S2 because there were so darn many.
He should stop forcing expansions into the universe and just start plainly telling stories. Once they just start writing and enjoying themselves with scripts, new characters will come on their own, and fit more naturally.
GIVE CLAIRE THE BEST STORYLINE When most people think of Heroes, they think of her. Give Claire something really interesting to do. She shouldn't be just stuck at home for another season bickering with HRG. She has the audience's attention, and it shouldn't be wasted. I can think of a lot of things to do with an indestructible person that they haven't done yet. Make her get into ADVENTURES dang it.
Let's explore this regenerative thing. What if Claire was sliced in half? Would that create two Claires? Which one would be the "real" Claire? Yes, that's been done, but not on Heroes. It'd be interesting if it was done existentially.
SOMETHING EQUALLY INTERESTING FOR THE PETRELLIS Meanwhile Nathan has some kind of (political) power again while Peter finds out he can't keep the powers he absorbs forever and they eventually fade away unless he comes into contact with the one who had them again. That way, Peter doesn't have to have amnesia anymore for a plot to carry any kind of challenge for him.
Claire's miracle resurrection blood is also dismissed in the same manner. It would be a HUGE mistake if they elminated the threat of death from the series entirely.
THERE'S A NEW THREAT THAT DOESN'T INVOLVE AN APOCALYPTIC VISION There are more ways to create tension than this. Season 3 is called "Villains," right? Make a good villain. A SCARY villain. A villain which the audience has no idea how could possibly be defeated.
BETWEEN SEASONS TWO AND THREE, MAYA AND WEST DIED This is casually mentioned in a conversation and never brought up again.
MOHINDER SHALL NEVER NARRATE AGAIN Shut him up. I groan every time I hear him speak over the beginning or end of an episode because his speeches are awful and cheesy.
I DON'T KNOW WHAT TO DO WITH HIRO because I'm one of the few that actually LIKED the Kensei storyline. I would have done exactly that, only the princess would have turned out to have a power, and she would have gone home with Hiro, and season 3 would have her awkwardly trying to adjust to the 21st century. But I guess not. So what do I know?
