I finished season 3 last night. Spoilers:
What the hell? Terrible ending. I'm mad at the writers for so many things. Maybe it's just me, but it seemed to portray all the women as selfish shrews this season--Jackie turning on Heather then betraying Frank, Heather turning on Claire and Claire, well she especially was written terribly and I hated it. All of Frank's missteps and problems were because of Claire. She acted completely out of character. I'm sorry, but after all they've been through and worked for, I just don't see her throwing the White House away like that. If you're the first freaking lady you suck it up and hang in there, especially if you're Claire Underwood. Her little outburst in Russia--what? Cold, calculating Claire of the past seasons would never lose control like that. I get that she has her own ambitions, but I always figured the plan was to pull a Hilary and run for President herself one day. I also get that this season was about bringing some of the characters back to morality (Claire, Remy, Frank, the Presidency itself), but it just didn't fit everything we've learned about Claire so far. They've already done the whole Claire running off thing. I figured the vow renewal would be a turning point that brought the Claire and Frank of old back again, but instead we just backtracked.
Heather Dunbar is, quite frankly, an idiot. Who gives up a lifetime appointment to the Supreme Court? That's such a better gig than President. So what, she gets her name on a list and gets to be the first female President, but she also gets the stress, the press hounding her every move, the exhaustion, the roadblocks from Congress, and it's only for 4-8 years. Or, she can sit on the bench as long as she wants and have a real impact on law and history. SMH.
Doug. What the hell, Doug? I'm glad to see him back at the end, but that was a weird shift. The Rachel plot is one of my least favorites. I just got tired of it. Too much poor pitiful Doug this season. I was glad he referenced Peter Russo, because the whole time I kept thinking we'd already seen that whole storyline.
The only thing I really loved was Remy. His shift to morality and leaving politics was totally believable. Also, it was really weird to see him not wearing a suit at the end.
There was too little Frank being Frank, and too much whining and crying overall. I spent the first two rooting for Frank and this one just feeling sorry for him. I hope next season is better, because this one just didn't do it for me.
