Here's part of the problem too: I have no idea in hell why HBO and Pizzolatto think each season has to be 8 episodes. Last season it worked just fine because you only had two people that the story revolved around. Almost every episode this season has been sightly longer than an hour and next week's finale is 90 minutes. That NEVER happened last season. Everything was under an hour and fit together well.
It's quite clear that this season needed a couple more (at a bare minimum) episodes to make things clearer and to explain the story better. I just feel like Pizzolato has handed his audience a 50,000-piece puzzle and said, "you have about 8 hours to put this together. By the way, there's no picture on the box for you to refer to so you can see what you're doing. Good luck!!"
