I watched the whole thing. I thought the alternate juror was interesting to listen to. He sure sounded intelligent to me and as if he took his job seriously.
They spent a bit of time on what the grandmother had to say, although I don't think it was valuable as far as evidence of anything goes.
I was glad to hear that Ashton only had positive things to say about the jury.
They focused on the relationship between Casey and her mother, which just adds to what the prosecution (and defense) did prove, that they weren't exactly an Ozzie & Harriet household.
The show did have some tabloid moments which I thought took away from it a little, such as near the end when they mentioned that Casey had had an offer to do a *advertiser censored* film and said that she looked like a Shampoo Ad Model (or something like that) for her sentencing.
