Maybe it's just me, but Sarah has a terrible view towards all technology. When she dreams of shooting the Manhattan Project team, she's throwing the baby out with the bath water. The boogie man of Skynet clouds her judgment and drive her to kill. Any scientist is a possible Skynet architect in disguise. Maybe that's what the dreams are all about. Maybe Sarah Connor doesn't want to murder lots of people with the outside chance that it might stop SkyNet from launching the missles. But one thing is clear, Sarah Connor can't kill people that she gets to know. Once names are attached to a face, pulling the trigger gets difficult.
The Kramnik vs Deep Fritz poster is a good reflection of Chess, and the moment when Sarah tries to figure out the cell phones after jumping forward over 7 years of technology was really realistic.
The worst scene was when John gets all familiar with the latest technology and apparently knows all about modern capabilities of computers in his talk about the Turk. John also has a real dark view towards scientists. Is Einstein suppose to be some awful demon that haunts the world?
Again Cameron is really awkward despite that brilliant display of emotions in the pilot. It's awful. You'd think that Cameron would try harder to be a high school student. I'm going to write it off as a terrible terrible error made in the pilot. Pretend that never happened and the series is nice and consistent.
But it's nice to watch Cameron start to pick up new slang. The girl committing suicide was just weird and distracting. I don't know why John was so choked up about the death. And you get a feeling that Cameron's definition of friend is more like being acquaintances. She tells John that someone who she has only had one short conversation with is now her friend. I think we can say that Cameron has no true understanding of what it means to be a friend.
