Dodgy Decepticons and chummy Autobots go head-to-head. Again. The third instalment of director Michael Bay's metal monster mash-up features his greatest conceit yet - imagining a scenario where American astronauts Neil Armstrong and Buzz Aldrin discover a crash-landed Transformer on the moon. This time round the villainous Shockwave takes the stage and traitors lurk in some very unexpected places. Shia LaBeouf returns as human hero Sam Witwicky, though Megan Fox makes way for British vixen Rosie Huntington-Whiteley in his affections.
Shia LaBeouf is back as Sam Witwicky, this time feeling very much the unsung hero of America's fight against the alien apocalypse. He has a new, rather lovely lady in the form of Rosie Huntington-Whiteley.
After saving the world on several occasions, Sam is now jobless, post-college and feeling a tad useless, an insecurity that is exacerbated by his girlfriend's smooth-talking boss (Patrick Dempsey) and the ball-breaking Head of National Security (Frances McDormand), who unfeelingly brands him "a messenger, not a soldier".
But of course, when a new threat from the Decepticons emerges, Sam seems to be the only one capable of putting two and two together - especially when traitors surface in some very unexpected places.
There's actually lots to like here: phenomenal special effects (a glass skyscraper spliced through the middle by the evil snake-bot Shockwave is a particular highlight) and some truly astounding 3D sequences.
The Apollo 11 conspiracy is also a clever premise, and there's some fun manipulation of real archival Nixon and JFK footage melded with the Cyberton sequence. McDormand and the great John Malkovich add some much-needed gravitas to proceedings too.
