The best shows do not need huge plot twists every episode to work. Many of the best Mad Men or Sopranos episodes were about nothing. One of the best Game of Thrones episodes ever was when Jaime, Bronn and Oberyn Martell visit Tyrion in the dungeon. Nothing happens in the episode, and it was great TV. I liked the way Better Call Saul ended the season.
I wish Halt and Catch Fire would slow down the jaw dropping events a bit and just tell the story. It was interesting for a few episodes, but it is getting a bit much. That was Boss' problem (the Kelsey Grammar show on Starz). The first few episodes were incredible, but by the end of the first season, the excess of insanity was starting to blur the show's overall plot. House of Cards is crossing this line too. It can't be shocking if it happens every week.
