Yeah! Now that I've managed to watch the whole series (8 years after it was made, but never mind) I can now make an informed decision about this.
There were some things I didn't like, mainly Cybertron originally being organic. Nowhere has this been even hinted at anywhere (yes, I know it's its own show and can do with as it pleases, but it doesn't mean I gotta like it). I also have a problem with Noble/Savage. It just doesn't mesh in my mind how a purely organic being can transform. In that respect, I totaly agree with Megs: organics have no place on Cybertron. Which made me root for him. He also makes a good point about individual minds being the reason for dis-harmony. But turning everyone into mindless drones is a bad move. So I was rooting for Primal in that respect. Which shows it had good plotlines when you want the hero and villain (even though I hate using those terms) each to win, but for different reasons.
I understand why people complain about the changes in characters from the established BW guys, but I also understand why this change took place, and that is one of the things I ike about it. I can even understand Ratrap making the deal with Megs and Rhinox changing his beliefs. He always did have a dark side to him hidden under the surface.
I loved the way BW used tribal/jungle beats for it's background music and this uses techno. A considerable shift that shows the differences well.
Plotwise, it was overall good. The darker nature of the series leant well but there were small things I was unhappy with: mainly Primal's obsessiveness with nature. But you can probably gather why I don't like that (I blame Vector Sigma's sex change for getting this obsession with nature all of a sudden
). But Megatron's plans and the whole 'Spark extracting' leant itself well into a tf show and those were great.
Finally, I thought Optimal Megatron was brilliant and a beautiful twist of irony, with a great chase in the final ep. However, 5 series worth of these 2 fighting ended rather anticlamitc IMO. And Silverbot's robot mode looked like a Chicken Run reject.
P.S. "I LIVE! I LIVE! I... What kind of puny body is this?"
