I watched it and came out very conflicted. For all of the reasons you mentioned, I found myself feeling bad for Harding, and believing that she honestly didn't know anything about the attack. The media constantly following and hounding her made me feel bad for her, too.
On the other hand, its hard to believe that she couldn't have known, and someone capable of such an act is probably just as capable of manipulating you into believing that they're the victim.
I thought, too, that they really tried to portray Kerrigan as the spoiled rich girl.
All in all, I thought it was very interesting and good.
I don't think they intentionally tried to portray Kerrigan as the spoiled rich girl, I think that is just how she came across. Which is unfortunate because I don't think she was a spoiled rich girl. I think that she was just so focused on doing what she needed to do that she did not have time for the distraction of the media. Therefore, she came across as somewhat aloof.
I was amazed that when her team was trying to decide whether to deal with the rehab or with the emotional trauma of the attack, Nancy was all about the rehab and had no interest in dealing with the trauma of the attack. I also love that when she went out to practice in Norway, she wore the exact outfit she was attacked in. A very mentally tough competitor.
