Judge for yourself if Revenge of the Fallen is one of the best films this summer: The blonde that Sam meets in college is a Decepticon disguised as a girl. She is given the nickname "Alice", since it was a copy of a humanoid Honda robot taken from an ad. This blonde seduces Sam, and as she inserts a probe (its “tongue” ) into his mouth to "hack" his brain, Mikaela enters his room and sees the girl on top of her boyfriend, and that pisses her off. Jetfire WAS a Decepticon that shifted allegiance to the Autobots. He was one of the original Seekers of the Allspark that reached earth thousands of years ago. When his “batteries ran out,” it must be that he is automatically programmed to retain the ability to copy any machine from a cart to whatever technology that existed throughout history while he lay dormant (not sure if this would be explained in the movie, which could be a source of a plot hole). Wheels, the Decepticon that Mikaela captures in her dad’s garage and after being threatened by a blowtorch, leads her, Sam, his geeky dorm mate, and Simmons to the Smithsonian to wake up Jetfire using that sliver of the Allspark that Sam had. Optimus Prime goes into stasis after being stabbed by Megatron (Optimus goes mano-o-mano with both Starscream and Megatron in that forest in the trailer. Optimus is not really dead, but it would take like hundreds or thousands of years for his body to repair itself). Sam ACTUALLY DIES, and while he is being revived, he sees a “heaven” vision of the original Primes and direct ancestors of Optimus, who were murdered by the Fallen, informing the teen that they have chosen him to own the Matrix of Leadership (It is the dagger-like thingy that Sam picks from the ground in the trailer; this was produced by the AllSpark thousands of years ago as a key to a machine atop the Pyramid of Giza that can destroy a star -our sun in this case- and transform it into Energon, a secondary energy source just in case the AllSpark gets destroyed). He hears Mikaela tell him “I love you.” And when he finally wakes up, his first words are “I love you.” A minor plot involves the fact that they haven’t said “I love you” to each other and each were challenging the other as to who should say it first, which complicates matters since Mikaela witnessed first-hand Sam’s propensity to be disloyal to him when he is far away from her. Sam uses the Matrix of Leadership crystal to revive Optimus' Spark. Before dying, Jetfire requests that his wings be given to Optimus Prime so that the latter could get to the Giza Pyramid fast, to stop the Fallen from activating the machine that could destroy the sun. Simmons has a major role in the film and becomes a hero of sorts. After being fired from Sector 7, he spends his time in his mother's deli, and he keeps a secret attic above his mom's restaurant, blogging with the name "Robo Warrior" who happens to be discovered by Sam's geek dorm mate. Simmons is responsible for helping out a U.S. Carrier with coordinates to destroy Devastator by sneaking under the biggest Decepticon ever. And Mikaela gives Simmons a flying kiss for helping her and Sam. I'm not sure how they would explain why Arcee is a girl, or the concept of trans-dimensional travel. At the end of the movie, once Optimus defeats the Fallen, Megatron and Starscream escape through a portal, a continuum a.k.a. trans-dimensional travel, and enter another dimension where the ship called the Nemesis is located. Megatron summoned the Fallen from this place. His last words are "Arise!" as he wakes up the other robots in sarcophagi in this ship. Megatron wanted to be a Prime, which is why he promised to work for his Master, the Fallen. Optimus, however, tells Megatron that he was deceived by the Fallen, since Primes are born--not made. The Fallen is a Prime that murdered Optimus’ ancestors, which is why Optimus is an orphan and the last of the Primes.
