Most TV programs last 60 minutes and anyone with intelligence (IQ of 100 or higher) can determine the "who done it" in about 15 minutes. Its refreshing to find a show that you can only get some answers on a weekly basis and these answers we compile them throughout the weeks and eventually it all becomes clear. Some people want the answer immediately and some will never get the answer. Its not about how intellectual the characters are and if they are intelligent enough to look out a window, its about how they react with each other. Some will click with another and will only be an accquantance with others; each has his or her own purpose. Has of the last episode, it is becoming clear that there is no escape, even if the "people" send a taxi and allow it; and now Joe is becoming a colorful character. Don't try to make more out of it than there is, take each episode and build upon what you know.
