I was not suggesting otherwise. It must be remembered though happy normal people are boring, so being a bit off is not a bad thing (in fiction). It would be nice if it did not go the complete opposite direction either, but everything has its advantages.
Its not like Bennett was completely normal. She was a mad, vengeful scientist besides being a sweet, shy girl( superb combination ).
Tess was smiling too a lot and she even went to a disco but meanwhile she was mad too and she had the ability to mind control people in a huge scale.
Its only that they smiled a lot.
Only problem with that scene is that it is probably not for real. Saying it is a problem is incorrect as that is how it is suppose to be. It is just that with this scene I do not know how to feel, whereas with River being happy it just feels great. Not bashing the scene or T:TSCC, just saying that it is very different emotionally to see Cameron like that rather than River. With Cameron it is confusing, which I am almost certain is the desired effect, and it worked magnificently.
That was exactly how it was planned. You wanted her to become a normal girl because her faked personality seemed so sweet and real. Then there comes a slap in the face when she does something inhuman and incredibly cruel. That was so thrilling, she played with the viewers emotions just like she played with Johns.
Another good example is when she pleaded John to not remove her chip in Samson and Delilah. There is a girl, crying and begging not to kill her, she looks so genuine and she tells you that she loves you. You know that she has to lie but even then your hearth doesn't want to believe it. Summer played it in a so moving way that you believed her totally and felt the same stress which was on John, believe to your hearth and risk being killed or pull out the chip despite she pleades you so much not to do that? I could fully understand how hard it was to John to pull that chip out finally.
It was totally awesome! When was the last time when you felt exactly what a character felt in a TV show? This scene could have easily been a disaster too. Only Summers ability to portray emotions so strongly is what made these scenes awesome.
