What is the finale of "Twenty Don't Confuse"? Why do netizens say this is the most perfunctory ending?

The finale of "Twenty Don't Confuse" is:

1, Zhou Xun went to Shanghai and decided to come back. Before he left, Zhou Xun confessed to Jiang, but Jiang refused. Weeks later, the story of Jiang and Duan Zhenyu appeared in the last episode. Duan Zhenyu filmed a video for Jiang abroad, which was recognized by Jiang's mother. It's great to see my parents. These three people are ambiguous, and the ending is also an open ending, without giving a substantive ending.

2. Luo Yan and Lu Ran broke up completely, and Luo Yan, who had always been disgusted with her mother, decided to get along well with her, which was a kind of growth after everything. Although I lost my love, I gained my mood. Duan Jiabao is the worst. He not only refused the bear who loved him the most, but also didn't get excellent love. On the contrary, he became a nuisance to the audience. Of course, the most perfect ones are Zhao Youhao and Liang Shuang. Two people who like each other finally open their hearts and come together, which is a perfect interpretation of cp powder.

Why do netizens say this is the most perfunctory ending?

The reason why netizens say this is mainly because the last episode is only 28 minutes, and the irrelevant advertisements and the opening and closing credits are cut off, which is only 23 minutes. Forget the length of time. The key is not to give the audience a satisfactory ending. Everyone has been looking forward to seeing the real cp of Jiang, whether it is Zhou Xun or Duan Zhenyu, at least give one. As a result, I didn't give any. Zhou Xun said before he left that he still had a chance. After all, Jiang is still young, so which pair of cp is the last? The audience is in a fog.

And Duan Jiabao and the bear. I thought Duan Jiabao would wake up and confirm his love for the bear, and then they were together again. Turns out they didn't play at all. As for what happened to them, they didn't explain at all. It is simply the most perfunctory ending, no one.
