I think the most interesting/scariest thing about the movie was the whole "company puts a chip in you" business.
This is actually becoming reality. They just had it on the news that a company wants to put a small chip in their employees so they don't have to log in, use credit cards in the vending machines, use keycards on doors, etc. I'm too lazy to find a link right now, but still... kind of creepy, IMHO.
