I was profoundly disappointed in season 3. The writing is substantially worse, and less smart, than it was in the first two seasons. The only reason I can think of for changing the basic nature of Frank Underwood, his marriage, his political savvy, is to intentionally frustrate the audience.
Remember when Frank Underwood was smart?
Remember when Frank Underwood was bisexual?
Remember when Frank Underwood and his wife stayed up all night plotting the deaths of their enemies?
That's all gone. Frank Underwood is now gay. Frank Underwood is now stupid. Claire is no longer evil. Season 3 spends *hours* asking the audience to feel sorry for Doug Stamper. I have no emotional investment in Doug Stamper.
I am really amazed at how badly they screwed this up.
