After watching Transformers 2: Revenge of the Fallen for 4 times in the cinema, I am surprised that I am still not tired of it... =)
Although we can take a look at the movie plot from a variety of angles, I have come to appreciate a more subtle theme in it - adulthood.
As Sam Witwicky started out in Transformers (the first installment) as a young boy thrusted into the midst of a civil war of more advanced robotic organisms, his main concerns was a hot college girl and his runaway car. Yet towards the end of the first movie, we see a more mature Sam, willing to risk his life for his heroic Autobot allies, putting him on par with the Autobots in courage.
In Transformers 2: Revenge of the Fallen, we see a Sam who wants to be normal as he deems the robotic civil war has ended with the death of Megatron. Yet, when new threats came, he was thrwon right into the middle of the conflict once more.
However, he was not condemned by his Autobot allies into joining them; its the sacrifice of Optimus Prime, altruistic leader of the Autobots, in the attempt to protect Sam that put a sense of deep conviction into Sam's heart, that he must revive Optimus.
(Sidetrack: This reminds me of a conversation I have had with a friend on non transformers related matters. As my friend of mine put it, 'God don't use condemnation to change us; He uses conviction to steer us to the right course and throughout the process, we retained the choice to act upon that conviction (for our own good) or ignore it.')
In a race against time and with the help of trusted and unlikely allies alike, Sam's efforts at reviving Optimus at the expense of his own life, succeeded in executing the rescue plan installed by the Dynasty of Primes, an ancient race of superior robotic organisms who predated the Transformers who are embroiled in the current civil war. He not only survived miraculously to revive Optimus, but in the process, has fought with dedication and courage befitting of a leader.
His taking charge of the situation when a cowardly companion Leo is losing it, and his convincing of his father to let him go and do what he needs to do reflects that of a maturing man.
From someone who is just interested in cars and girls to someone who sees the greater purpose beyond himself, and to press in with great faith even in the midst of great uncertainty, he has proved himself a worthy leader and a real man.
In each and every one of us, we are inputted the ability to recognise and respect things that are noble, virtues such as courage, integrity, wisdom, responsibility, This should be how we live our lives. As Seymour Simmons (John Turturro) exhorted Leo in Transformers 2 when confronted by the mammoth like decepticon Devastator, 'If we have to go down, we will go down like real men!'
A visibly subdued me walked out quietly before shooting back a question, 'How did you know I didn't have one [girlfriend]?' BLEAH
