The only upvotes I'd have for Prime was the great voice acting, smooth animation and somewhat tolerable humans. Everything else is garbage.
First off, the show has no purpose whatsoever. In Beast Wars, the purpose of the show was to figure out Megatron's plans and stop him from changing history and reaching Cybertron. In TF: Cybertron, the purpose of the show was to find all of the Cyber Planet Keys before the Decepticons do. In Animated, the purpose was to find all the all-spark fragments before the Decepticons can, you get the point. Now, somebody tell me what was the main plot/purpose of Prime? It seems as if every storyline (Predacons, Relic Hunting etc) lasted only a few episodes.
Second of all, character development in TFP is terrible. Optimus becoming more violent at the end of season one was referenced in only two episodes in season two, and never in season three. Arcee realizing that her desire for vengeance was wrong in Partners was immediately forgotten in season two and she continued to run off to get vengeance. Starscream realizing he isn't the ultimate Decepticon at the end of season two was quickly forgotten in season three, where he became threatened by Shockwave, despite having no good reason to, seemingly because he was too egotistical to realize not everyone wants what he has.
There was also problems with the main characters. First, it was Arcee in Season 1 and there seem to be no season 2 main character until Smokescreen came along. Then Bee became the main know what I mean
Finally, the drama behind the show oh god. Each episode cost so much money at one point that it prevented Hasbro from investing further into Transformers and it aborted so many good storylines and arcs.
Oh and bonus, remember when Ratchet mentioned that if the traveled outside of the Earth via groundbridge, the vortex has a great chance of snapping and sending them to random areas in space? Well they were able to go outside of Earth TWO times via groundbridge, even traveling to Cybertron with no problem.
4.5/10 This show has so many problems its hard to look at the good side.
