It is true that 40 episodes of a good drama are generally enough, but whether 40 episodes are enough is not one of the criteria for measuring a good drama.
Compact plot is a good thing, but today's domestic drama plots are delayed again and again. On the one hand, there is indeed a long-term consideration of making more money, but the most important thing is that the level of screenwriters is really poor.
The poor level of screenwriters is caused by many reasons. One is that the review system is too strict and there are too many restrictions on screenwriters. On the other hand, the current capital is eager for quick success and instant benefit, and is overly superstitious about big data and enthusiasm. Squeezed by these two reasons, the scripts that can finally pass the audit and get the favor of capital are generally poor.
To change this situation, the most important thing is to standardize the censorship system, which cannot be changed overnight, relax censorship and give viewers more power to censor film and television works. At the same time, good scripts must be praised and rewarded at the official level to encourage creators to write better scripts.
Back to the limit of 40 episodes, this method is really useless.
You know, even if many TV series are shortened to less than 40 episodes, the plot is still very protracted. However, if the script originally planned to be shot at one time cannot be shortened to less than 40 episodes, the film may not be finished at all, and the rest of the story will be shot in the second season, then the restriction policy will lose its meaning.
Moreover, although most dramas can be controlled within 40 episodes, it is undeniable that there are quite a few excellent dramas with more than 40 episodes, such as Kangxi Dynasty, with 46 episodes. Which of the 46 episodes of Kangxi Dynasty is better than today's online drama?
