WARNING: POTENTIAL HOUSE OF CARDS SEASON 4 SPOILERS
Not sure what to make of this season. On one hand, I think the show is entertaining, extremely well acted (with one glaring exception that I'll get to), has some terrific characters, and the first two seasons are fantastic. On the other hand, while we were always supposed to suspend disbelief, I do think they're getting close to jumping the shark and they need to be careful.
Some of the stories are just too eye-rolling. Yes, Claire's connection with Tom Yates sheds even more light on her character (and she is the MVP of the show, which says a lot since Spacey is spectacular as you'd expect), but seriously? The first lady of the United States having an affair with some writer, while campaigning, no less? And all things considered, they're not even being THAT discrete about it.
Things really took a turn for the outrageous towards the end (from Conway's family stay at the White House to the live broadcasting of a terrorist beheading... Again, it's good TV but it's a tad disengaging given how unbelievable it is (especially the latter).
My final gripe with the season is how horribly miscast Conway is. He got better towards the end but he's completely out-acted by everyone around him.
It's still a great show and well worth watching.
