Generally speaking, there are few commercial works of animation, because Japanese animation is based on comics or novels, which is the so-called animation, unlike the adaptations written on various TV dramas in China. The word animation refers to the original cartoon or novel that is displayed in the form of animation and put on the screen almost without modification except for some restricted or unreasonable elements. For example, the difference between the original sword and the animation is that an illogical plot is deleted from the animation, while other parts are made completely according to the original work.
Adaptation is a different story. With it, the screenwriter will modify the original according to his own ideas or the wishes of the production company, and then make a TV series or animation according to this script that is not the original. This is adaptation.
Xianjian TV series is the best example of a commercial film, which only keeps the main line of the original, and the other contents are completely fabricated, incorporating a large number of popular scenes at that time, catering to the tastes of the general public only for making money, and completely ignoring the original story "attracting the audience to the maximum" is the biggest feature of commercial films.
If you still don't quite understand, you can refer to a pair of old movies of that year. You are friends with two directors in Time Has Changed, Liu Zhenwei and Wong Kar-wai. When Wong Kar-wai filmed Ashes of Time, it was difficult for the general audience to understand because of its deep connotation. Although it won many awards at home and abroad, the box office was bleak and even made ends meet. There is a simple reason. In order to improve the artistic value of the film, Wong Kar-wai greatly enriched the connotation of the film, and the almost disordered arrangement in time and space caused the audience not to buy it. So a movie with high artistic value only got the box office of a third-rate movie.
After that, Liu Zhenwei filmed Dong Chengxi with the original crew of Ashes of Time, which is just the opposite of Wong Kar-wai's Ashes of Time. Although Dong Chengxi didn't win any prize and didn't have any profound connotation, he was the tenth of the top ten blockbuster movies of that year, and the box office was dozens of times that of Ashes of Time. This is a typical commercial film, which does not need any connotation or earth-shattering story, but only entertains the public and caters to the public's taste, that's all.
