I found the Diane Sawyer interview very moving -- there was some genuine truth and struggle in what Jenner and the family members had to say, and some valuable information as well.
The reality show, not so much. I watched the first episode, and it came off as very forced, trying to be all things to all people. You can either do "Lifestyles of the Rich and Famous," or you can do earnest activism and education, but trying to combine them doesn't work. I admire Ms. Jenner for her courage (although I'd like to think she might say, as I have, "It's not courage, I just want to survive"), but she doesn't, um, have a dynamic, charismatic presence.
In particular, her "activism" seems very scripted, and I think she's dangerously close to coming off as some sort of white savior, Lady Bountiful type -- which I would find profoundly offensive.
I doubt that I'll watch the show again.
