Transformers: The Last Knight - Bay exits with a soulless bang
For his final tour of duty in the Transformers director's chair, Michael Bay doesn't go out with just one bang, he unleashes a barrage of ground-shaking booms.
The revitalised Decepticons, led by Megatron (voiced by Frank Welker), hunt for Merlin's staff in order to bring about the end of the world.
Alas, Optimus Prime (Peter Cullen) cannot lead the fight: he is tumbling through space, bound for the planet Cybertron and his creator, Quintessa (Gemma Chan). Consequently, fugitive inventor Cade Yeager (Wahlberg) answers the battle cry, aided by a plucky 14-year-old orphan called Izabella (Isabela Moner) and his Autobot comrades.
Transformers: The Last Knight is unlikely to win new fans to the franchise, hanging spectacular yet soulless special effects-laden calamity on a gossamer-thin quest for an Arthurian artefact.
Throwaway sub-plots about parenthood, self-sacrifice and unity are tossed into the melting pot without any purposeful design.
