After watching the movie, "Total Recall" (first one) I wondered why anyone wouldn't want to live there... at least the first 1,000s of people. It's hospitable to humans and mutants alike and it has a nice structure over the city, which is a security risk if penetrated to be honest. This thought might be way off per seeing one movie, so I'd love to hear someone tell me otherwise..... like why inhabiting an enclosed city hospitable to humans isn't a good idea.
