Second ep answered a lot of questions. They did hint at T3 and a pretty clearly explained that this show's time line is divergent from the original movies due to the time skipping. The fembot is definitely more than just a protector, she was most likely altered to try and make her more human. She is very much like a child, learning by mimicry and then attempting to improvise along the lines of what she's experienced (like Arnold in T2 but to a much greater degree).

One glaring inconsistency that bothered me was that Sarah and John were able to pick her up, she has to weigh a good deal more than she looks like she should.

Anyway, I like Sarah, I like fembot (couldn't make out her alias) and John doesn't seem central to the stoy anyway so his lameness doesn't bother me much. The Hobominater was another big plot hole...if it came back fully functional but headless why the hell didn't the gun or pieces of the vault come back... still I'll watch for the fembot's growth and Sarah's ass kicking, I only made it 3 eps on Bionic Woman before I had to give it up doe to boredom, hopefully this won't have that effect.
