They do build up wrong. That's why people think it's going nowhere. The antagonists are aimless and have little effect on the protagonists. One antagonists spends several episodes dealing with his mean mom, while the other spends another few episodes dealing with jurisdictional issues. There's no cat and mouse. There's no building of suspense between episodes. We have these characters who are supposed to be important do nothing but go through files coming no closer to catching the protagonist. That's not build up.
