Ah, yes, the sequel to Michael Bay's 2007 hit, Transformers, pits heroic Autobots against evil Decepticons, as a new threat looms over the horizon. Some new Autobots arrive, Mudflap and Skids, who are mostly comic relief. They even had the Constructicons, who transform into Devestator. They actually showed Devestator's "balls."
Jetfire was an SR-71 Blackbird (the X-men's jet), and Wheelie was a kids's toy car. They had a Decepticon infiltration unit who could disguise herself as a human female to get to poor Sam. Soundwave and Ravage were awesome, and the interaction with Starscream, the coward he is, and his superior, Megatron, was classic.
The Fallen was a Decepticon, who corrupted Megatron, and then pretty much Megatron adopted his visage as the current Decepticon symbol, which all Decepticons in the movie sported.
