S1 heroes was an amazing origin story.
Then S2 was...MORE origin stories! Followed by season 3 of origin stories! and another! Lots of origins!
I haven't seen the new one, but I guess I just assumed it was going to be more origin stories with cliff hanger endings.
The cliff hanger endings is another topic entirely, but the short version is: you have to be DAMN good for me to be willing to put up with that nonsense, and if I know you're going to pull that crap going in, you need RAVE reviews or I just wont bother.
Now..if you told me they were planning to pick up where S1 left off, ignore all the other seasons, origin story is done, finally get to heroes fighting villains...yeah I'd be on board. Throw in a promise of "We'll end the episodes or at least the season with the natural story-breaks rather than artificially creating summer-long suspense by ending everything 5 minutes after storylines start" and I'll even pre-order.
But this? I honestly wasn't planning on even giving it a chance unless people here were singing it's praises, and so far...I don't hear no singing.
edit:
I've been watching so far and while it's not as good as S1 Heroes it's not bad. It does seem to be building to something big and it seems to be moving towards the heroes actually teaming up, something that they really didn't do until the very end of S1 and even then only briefly. The biggest criticism that I have is that the overall background plot isn't terribly original, basically a rip-off of X-Men and the whole Mutant Registration Act storyline.
I wouldn't mind a rip off if done well. That's a story that would be really good in TV format. One of my major complaints with Heroes always was that it ALWAYS felt like it was building to something big. But it never happened. I guess...let us know if it ever gets anywhere. But if they are just going to do another 4 seasons of building to nothing...pass.
