I am only halfway through the series, but am enjoying the whole thing. I don't know what all the hate reviewers are watching, but I like Renee Zelwegger playing the evil role; I like the leads and the subplots, especially the gay storyline. Other reviewers are holding their noses and watching, but get over it, folks; the LGBT community is part of life, and their stories are as vital as any.
The subterfuge and twists remind me of Revenge, which I loved.
So, don't think too much about it. Just relax, and enjoy the pure soapiness playing out.
