Brothers-in-arms Orion Pax and D-16 become sworn enemies Optimus Prime and Megatron.
This was easily the best Transformers movies since the original. However that is not saying much because I am not a big fan at all of any Transformers movies outside of the first one. This did have a good story and some pretty cool animation. Giving us the origins was a pretty good idea but like at this point I'm just not sure how much anyone can really care any more.
I would kind of recommend people checking this out. It is absolutely not a must watch but it is a much more decent watch than most of the live action offerings.
