Movie origin stories finally reach their nadir this week with “Transformers One,” the super-violent, toy-selling vehicle that tells the tale of how Optimus Prime and Megatron went from besties to foes,

As origin stories go, director Josh Cooley's breezy, action-packed genesis tale reintroduces Optimus Prime, Megatron and the rest of the Transformers gang, without any pesky humans hanging around the edges of the frame to muck things up.

Transformers One doesn't just change the history of Optimus Prime and Megatron, it also changes the original meanings of the names Autobots and Decepticons.
