How to evaluate the beginning of TV series?

At the beginning of the year, the suspense drama "The Beginning" burst into red, and the word-of-mouth ratings were excellent, which made people sigh that the new spring of online drama has come! The reason why this unlimited traffic online drama is on fire may be because of its "unsolved" and "blank". Although sometimes this kind of blank will bring a feeling of regret, it is this kind of "blank" that gives the audience enough reading space and makes the play more popular.

First, what's in Wang's mobile phone? After all, the ringtone of this mobile phone is an explosion warning ringtone in the play. At first, the bell was repeatedly emphasized, but in the end it was understated. People can't help but wonder if there is another article about this ringtone and the contents of the phone.

Secondly, there is a car next to the No.45 bus, with a father and son inside, which brings warmth to the whole drama. At the same time, children and fathers can also observe what happened on the bus from the perspective, which actually constitutes a bystander perspective. I thought they would intersect with the main line of the story or provide some clues, but in the end there was no more ink to describe them in the script. Maybe they are the embodiment of warm human feelings.

Third, why is Xiao's body getting weaker and weaker, even to the point of vomiting blood and unconsciousness, while Li's poems are safe and sound? It seems to involve how the cycle came into being, why Li Shiqing was the first person to enter the cycle, and so on, but these problems are just not explained in the script and need the audience to supplement and imagine.

Fourth, Xiao's identity in the play is a game architect, and he opened a game development studio with his friends. Other branches of the play are mentioned more or less in the ending, but the branch of He Yun Jr. and Liu Peng's career line and brotherhood is completely ignored in the ending. If you can echo it later, it may make the plot icing on the cake.
