I am not sure if it is because I had just finished watching Energon but I really liked Cybertron, becoming my second favourite Transformers series after Robots in Disguise. While it seemed at the beginning that the story wasn't the best since it was just one big fetch quest, there were some surprising moments and I started to really like it at the second planet. I loved the arc about Vector Prime, I actually felt emotional about what he had done, it was one of the best moments in the cartoon. The series also built up to a nice climax, and the final battle between Optimus and Megatron was awesome.
There were some nice Optimus combinations here, too bad that they didn't translate that well into toys (if you think about it, savage claw mode is Leobreaker forming Optimus' arm, super mode is just a wing pack and extended legs, and sonic wing mode is only Wing Saber strapped onto his back with a new chestplate, nowhere near as complex as RiD or Armada's combinations). The transformation stock footage were well done and visually interesting (I really liked the banter and constant talking in them), but were used way too much.
I didn't find the kids too annoying. The animation took some getting used to but nowhere near as clashing as Energon's cel-shaded animation. The music was good. There was a lot of good humour. Overall, a solid series and worth watching.
