Plot

Main event: Cybertron on a collision course with Earth and the search for Merlin's staff.

Optimus Prime flies to ruined Cybertron, where the sorceress Quintessa bends his will and sends him back to Earth as Nemesis Prime. It turns out Transformers have shaped human history for centuries, even helping King Arthur, and gave Merlin a powerful staff. Cade Yeager, Oxford professor Vivian Wembley and Sir Edmund Burton race to find the staff as Cybertron closes in on Earth. Bumblebee's voice brings Optimus back to himself, and the Autobots stop Quintessa.

Archive review

What works

  • The idea that Transformers have been alongside humans throughout history, including King Arthur's time.
  • Some spectacular shots and Jablonsky's recognisable music.

What doesn't

  • A convoluted plot that is hard to follow.
  • Optimus's turn against humanity is resolved far too quickly.
  • Frequent aspect-ratio changes are distracting.

Who should watch: For completionists watching the whole series in order.

Verdict — 4/10. The weakest film in the series: interesting ideas lost in chaos.

This is the Archive editorial opinion, not audience reviews.
