Don't get me wrong, I think the writers did a great job trying to explain how Cybertron died, and why everyone left the planet, and the origin of the matrix. I loved that bit. However, they alluded to a past that Megatron and Optimus shared which they never finished. Also, Optimus told ironhide that there were reasons why he hadn't stepped up earlier to be the leader, again with no explanation. And Finally, I thought the last scene would have been an all out battle between Optimus and Megatron and the two factions, but no such luck. I absolutely loved the campaign story...it was great, but did anyone wonder about these items I mentioned?
