Why is the score of costume drama so low now?

Looking at the synopsis of the story, the play "Xinghe" is quite interesting. Young girl leaves on the grassland can predict disasters. In troubled times, she relied on this talent to become A Qin Tian Jian (in layman's terms, she was the fortune-teller of ancient kings), and then fell in love with the bloody king Mi Ming Xiu, but there were also stories of misunderstanding and entanglement. I am 44 years old this year, and I have no sense of cp with the heroine Peng. Especially William Feng's grassland costume, this big scarf, directly covered his neck, and the state of his face also appeared greasy and vicissitudes. The Trial World is a big IP drama adapted from the novel of the same name. There are quite a few books in this play, and it has its own flow. The actors are Yang Yang and Zhao Lusi, the top actors in the entertainment circle today, which shows the popularity of this drama. However, the douban score of this drama is really not proportional to its fans. Douban score is only 5.7. If it is a score system of 10, Trial World has not even reached the passing line. Please teach me more about the rest of my life, which is also adapted from the novel of the same name. The composition of this drama is somewhat similar to "Try the World", and it is also a way for big ip to add top flow. Andy and Sean, the leading actors in this play, are both top-notch, and the power of their fans will really scare you. The play was broadcast in March, and the douban score came out in June 65438+ October. It's been half a year and I don't know what happened. The douban score of this play is only 6, just reaching the passing line. At the beginning of the year, after "On Earth" ended, "In My Heart" took over, and Christina partnered with Tan Ya's double actress combination, which made people instantly full of expectations. After watching several episodes, the audience found something wrong. It is really not easy to find some "normal people" in Living in the Heart. At the end of the TV series, not only did Gu Qingyu, the eldest sister-in-law, give her the house across the hall, but local tyrant Zhanxiang also gave her a 0/0% stake in the nursing home, which made people call the end of the TV series and let themselves go directly.
