Hmmm, I wonder if the generic decepticons will do anything cool like transforming ? or combining or triple-changing. How about all those big ships entering the city could they possibly transform into really big robots? The tentacle thing ripping a building in half, that looks promising. A whole lot of non transforming drones I would be ok with to bulk up the ranks of the invasion.
They could do some really mind blowing stuff, but I mean more than just big spaceships and robotic giant aliens. Honestly I like the trailer, I like alien invasions, but I don't like wasted opportunities, or lack of imagination.
