The TV series "July and An Sheng" has poor ratings. Is there a problem with casting?

I think it is not only a question of casting, but also one of the problems. First of all, from the original novel July and An Sheng,

This is a short story, and it is not particularly long. Secondly, July and Ansheng grew up together and later fell in love and killed each other. The two people's character opposites are particularly distinct. Then, in terms of ratings, a good work is first the role, then the plot, and then the details, such as the handling of characters, the handling of pictures, clarity, photography and so on. The film Three Silly Bollywoods won the best cinematography award. The TV series "You know, you know, it should be green and fat and red and thin" is about details.

The site layout has been well received by netizens. But in general, a good drama is driven by characters and plots. The appearance of Chen Douling and Shen Yue makes people feel that there is no special charm. But in the movie version, Zhou Dongyu and Sandra vividly presented the two images of July and An Sheng to the audience. So I think maybe their acting skills need to be improved, or maybe they are not suitable for this type of TV series.

It may be more suitable for campus youth types. In addition, the plot of the TV series "July and An Sheng" is too long, and some dog blood plots make people no longer interested in watching it. The plot is not particularly helpful to the novel, but it dilutes the original taste of the novel. I saw some netizens commenting that the TV version felt that they were not real sisters, but more like a pair of plastic sisters.
