I think shows that don't have an end in mind always devolve into their purest form

Like Suits, a great example of a show that just went past its life time. It eventually just became people barging into someone's office and yelling at then over something they misinterpreted, usually with some form of "oh here's a gotcha I also was doing stuff behind your back" only for the person they're yelling at to reveal it was either a lie/misinformation or hit them with a gotcha of their own, then they walk down the hall and get yelled at by some temporary character
