I'm not trying to argue that kids aren't stupid. I'm saying that Sam Witwicky selling antiques to make money to buy a car was a stupid plot device. Not only were they antiques, they were literal family heirlooms. And not only did he try eBay, he tried selling them directly to his high school classmates to be used as Columbus Day gifts. Again: a plot device in TF1 was Sam trying to sell his classmates antiques as Columbus Day gifts. People really don't give this movie enough shit for being awful. Because it's pretty awful.
