I think Queen of Versailles failed on a number of levels--primarily because it didn't seem to take a strong point-of-view about the main character. I'm sure the fact that she's listed in the Playbill means she had some degree of feedback, which I strongly suspect kneecapped the project. All of that said, if it failed, it did so with ambition. It was all over the place, but it TRIED.
Redwood, for me, was borderline unwatchable. One of the ugliest physical productions I've ever seen, but more than that, it somehow found a way to make the most sympathetic character, a woman grieving the loss of her only child, seem...not UNsympathetic, but...borderline.
My completely subjective take: Queen of Versailles didn't work, but I HATED Redwood.
