How to distinguish between American dramas worthy of attention and American dramas that are decisively abandoned as soon as possible?

I remember when I was a child, the first American TV series I came into contact with were TV series introduced by TV stations such as Growing Pains, Knight Rider, and Defense Lawyer. Defence lawyer has been searched on the internet, but it has not been found. Maybe I got my name wrong. Because American TV series is broadcast while shooting, the ratings directly affect the length of the series. Maybe the series is not popular, and it will be gone after one season. But if the series is very popular, they will continue to shoot. I think this is the worst point of American TV series. Some dramas have low ratings, but there are still some loyal audiences, but these dramas have been ruthlessly cut down because of ratings. The whole story is not finished at all, and the ending is sloppy, and some even have no ending. In fact, good ratings are also very problematic, that is, because of good ratings, the film will continue to shoot, and slowly you will find that the story of the series is getting more and more outrageous, because in order to push the story forward and look good, you have to constantly introduce new characters, and the framework of the story is slowly getting more and more chaotic. But you've been watching it for a long time, and you don't want to give it up. You can only put up with this smelly and long story. Until today, I didn't understand how Growing Pains and Charlie Hebdo ended. Similarly, "Desperate Housewives" and "The Romance of Mom and Dad" also started with the protagonist's suicide. The suspense of the whole drama is why the protagonist committed suicide, and the story became more and more confusing as I watched seven or eight seasons. After watching seven or eight seasons, the story becomes more and more confusing. I'm not even interested in the reason why the hero committed suicide. Although it was over, I didn't stick to it in the end, and my interest in reading was gone. The other is a suspense film that promotes the development of the story based on who the protagonist's wife is. The same is true, endless, and the main line basically does not promote the development of the story. Gave up, too So I recommend a TV series with one or several independent stories. In this way, even if the animation is as long as Conan, a primary school student, it will not affect the plot. For example, relaxing dramas such as "Make a scene in Heaven" and "Waste Wood Alliance" are also good. Or a series supported by a complete story, such as Game of Thrones, with the original novel, even if there are some changes, the big framework will not change. It won't turn into a big pit. A series with an independent story in a season like American Horror Story is also very good.
