As what would you expect from a film by Bay, the film's full of fast-paced action, explosions, mayhem and lots of explosion.
SPOILERS
Film starts with a narration by OpPrime (voiced by P. Cushen), telling us about their war in Cybertron, how Allspark was lost. We get back to Earth as Sam narrates about how great his grandfather is to his class. Sam gets BBee, impresses hottie Megan Fox. The Military Base in Qatar was attacked by Skorpkop, but Josh and Tyrese survived. Peter discovers his car was a Robot, and soon he was being chased by Barricade, one of the Decepticons. BBee saves him, mets up with OpPrime and the rest of the Autobots, and explains everything to Sam. Here Sam found out that the map to Allspark was accidentally transferred to his grandfather's glass, after discovering a frozen Megatron. Ratchet also detects that Sam wants to mate with Mikaela. They were intercepted by Sector 7, a top secret military organization that have been hiding the Allspark and the frozen Megatron. The Decepticons located Megatron and frees him, Josh's and Tyrese's team was recruited to take down the invading bots, and what follows is the cool robot action with lots of explosions and destruction. OpPrime calls the rest of Autobots, StarScream survives, and Sam gets to kiss Mikaela on top of BBee.My favorite part:
Sam's level of pheromones as detected by Ratchet
and Sam's "Happy Time".
but it was very nostalgic and most of all fun!
