Ugh... I suppose I'm going to have to explain WHY it was the perfect ending now... I didn't think you guys were that slow.
Ok the thing you've got to remember is there isn't a main character in Heroes, it's written in such a way that depending upon who you favor,there are about three or four. The problem with that is everyone wants their main character to save the world, and the way the finale was written, this one could argue that any of the three or 4 did.
First you have Peter, he's the obvious choice for all the dumb "darg what's a sub-plot?" fans out there. He's the typical generic hero guy, so of course he must save the world. He does by standing up against Syler and preventing the bomb. Next we have Hiro. He's our number two guy and your typical underdog type of hero. In typical foreshadowing fashion, he pretty much dreamed of being special and being a hero before he was even aware of his powers. With all of his speeches of destiny and what's right, he had to save the world. By stabbing sylar he did. Now with all of this "save the cheerleader, save the world" business clair had to be involved, and she was. She, along with peter, changed the heart of Nathan, so she, indirectly saved the world. Getting on to Nathan..... he ws more of a dark horse that was too subtle for people to get early on... I caught it though back towards the beginning. Probably the most well thought-out plot of the show was his transformation from a greedy, self-centered conservative into what being a hero is really about, caring for others before yourself. He literally saved the world, and in grand star trek 2 style no less.
Now for the main sub-plot. Nikki was never meant to save the world, she was meant to save herself. Her struggle with Jessica for control or her life and family was sybolic of our own struggles of moral question. With her giving that solid whack at Syler, it marked her first self-less act, (had nothing to do with her or her family) and showed that she was on the mend.
Let's see more minor plots..... Seresh found closure by saving the little girl and coming to terms with his birth being mainly to save his sister. The cop....(sorry his name has slipped my mind). Early on in the show he talked to his wife about what it would mean to him to be a detective, to do good, to be a (wait for it....) hero. The little girl's plea as he's hauled into the ambulance full-filled his destiny. And of course dark-rimmed glasses plot is fairly self-explainatory, he came to terms with the fact that maybe what he's been doing all these years wasn't for the greater good and went to fix it. Now that he can stop living a lie, both literally and methphorically, he can put his family back together. Clair of course learned the very "after-school special" lesson that being different doesn't make you a freak, it makes you special.
Yes I saw the bloody trail, it should be obvious at this point that I pay a little more attention when watching a show than the average viewer. I don't want to give away my theories yet, but lets say that Syler was more likely "collected" than an escape.
The Hiro in the past preview was a little predictable, but it'll be good. An introduction to Kenzei (who I also belive is related to Hiro's dad, but not that way) will put light onto the fact that the mutation is not as new as we were to believe in the beginning, and of course explain what the deal is with that shoosh symbol popping up all the time. While he's in the past for the beginning of season 2, the others will uncover the previous generation of hero's in the present and their role in a planned aocalypse (that'll tie in to the collected bit I theorized about earlier).
In case you guys didn't figure it out, of course peter isn't dead. He'll fall to earth eventually.
Ok that sums it up pretty much.
Now for responses to other comments.
No Jericho was about the action, and heros was about the interpersonal relationships. What the shows should have been in your opinion or what they started out as, has nothing to do with how they actually turned out. The meat of every Heroes epsiode was about the relationships between the characters, with mild pauses of bad-ass action. The meat of every Jericho episode was our invincible can't die boy going out and shooting half of the surviving world a-la 80's action flick with mild pauses of interpersonal back-story. I rather liked Jericho, but more like how I like a "so-so" sic-fi drama. I really enjoyed it and I think it had another good season out of it, but "eh" I can live without it. Can't say the same for heroes. I mean Jericho's main plot points (I mean that literally, there are only two) kind of phizzled out 5 to 10 episodes before the finale. The bulk of our questions were already answered too soon, and badly I might add, so that after the break, a lot of people didn't bother to finish up.
My comment on Lost should have been obvious. It's nearly impossible, in this day and age, to loose an entire airplane on an island... especially with survivors. The show was flawed before it even began. To combat this obvious flaw, the writers invented lots of crazy scifi-drama excuses, ever-increasing in their levels of b.s. This is pretty much the plot of gilligan's island. People like the cast-aways on the island, so they can't leave the island, so every time they are close to escaping, they need to pull a "Gilligan" so they can't leave. No I don't watch the show, I didn't even watch the first episode. I do know people that watch the show though, and unfortunately talk about it constantly, that's how I know about it. Much as I predicted, it started to fizzle out after season one and never really recovered.
Hope that clears things up... actually think about the heroes stuff btw. If you can think of a better ending that satifies the requirment that all of the plots and sub plots I highlighted had to have some full-filling closure then I'd like to hear it. It's a delicate balance on a show like that between giving the fans too much of what they want and thus making season 2 pointless, and not giving them enough, thus making it another lost and driving people away.
