The seemingly innocuous road vehicles that can change at the flick of a switch into mega-destructive robots trundle out for more metallic fisticuffs in this blockbuster sequel. Devious Decepticons Starscream and Megatron (the baddies) have renewed their heavy metal assault on humankind, whose steel allies the Autobots (goodies) led by Optimus Prime, have fallen out of favour with the US government. The fools. Shia LaBeouf and Megan Fox play the lovey-dovey couple caught in the middle. Again.
