Obvious from my previous posts I have been reading into the plot holes in the movie. Before someone jumps my case its not that I have anything against the film...its simply because I figured some people would have support and reasons behind some of these plot holes in defending them.
In my search I came across the answer to one plot hole that some people were wondering about...
I got this little tidbit from a response to someones complaint on a message board.
If only a prime can kill a prime....then how the hell does Megatron and his goons kill Optimus if Optimus and The Fallen are the last two primes?
Answer: Optimus didnt die....in the novel it states that Optimus didnt die and went into a system shut down mode. The system shut down mode was to allow Prime to heal but the healing would have took a few hundred if not more years to get him back online. Thats why Sam needed to retrieve the Matrix....to speed up the healing.
