Let me tell you a honest review. First I was sceptical seeing the animation and not finding them good like they didn't look anything like Optimus or Megatron. As the story progresses and you see the changes it all makes sense. All those movies and animated series of transformer had the same fight between Autobot and decepticons . None of them showed the back story of how optimus became prime and how his and Megatron's friendship ended. Because of the backstory this movie is better than other in my opinion.
