Spoiler character and theme info from movie writers.

[MV75]

?It?s about being away from home. It?s a few years later and Sam is going to finally go to college and he?s going to face being away from home just as the autobots are having to deal with being away from Cybertron.?

Anyone else unnerved by this?

I can see the third movie:

Sam gets a job and buys a house, mows the lawn on the weekends.

The transformers also get jobs, buy a warehouse to live in and mow the ener-grass and pull out the ener-weeds. And every year they all go the the accountant and do their taxes.

Then the ending is where they're all playing bingo in the old folks home, and instad of peeing on s7 agents, bumblebee just pees all over himself. The end.
