I like the fact that the characters are really well fleshed out have their little quirks. They also do a good job in showing what you might call their human side. I remember one time when Carter was telling O'Neill something complicated and he interrupts and asks, "are you telling me that you can make him visible? That's all I need." Cater showed the frustration really well. Another one was in Frozen. Right after they arrive in the Antarctic O'Neill throws a small fit and Teal'c give him a questioning look. O'Neill looks back and states, " I forgot to tape the Simpson's." Teal'c responds with an "are you serious" look. O'Neill responds, "It's important to me." Small things like this really set it apart from other shows, at least to me.
