As with so many modern scifi movies and TV series the characters look, talk, behave as though they just moved there from an American city. If these people are descendants from people who first moved into this Silo 200 years ago due to some catastrophe on Planet Earth, they would not look or sound or behave like people you would meet today on 42nd St. NYC. They would have developed into people totally different. Would George Washington or Lord Nelson, if they showed up today look or sound like us? No, of course not. Having said all that I find Silo to be an original idea that makes yiu want to find out just why the Siko is there in the first place.
