However, as they are attached to symbolic models, some movies are used to develop symbolic models and fight fundamentalist tendencies and as such, have a positive impact on society.
A huge danger associated to art movies is blocking the capacity of people to think independently (tendency towards induced schizophrenia XS1B). Each script is a long-range symbolic model; thus, the movie as a whole is logical. This long-range symbolic model is translated or associated to a long-range image model. If the translation is correct, the image model will be harmonic as well. Thus, an art movie is a logical and harmonical long-range image model. The fundamental problem is that it is not enough for a model to be logical and harmonical in order for it to have a good connection with the external reality.
There are movies that try to reconstruct an external reality that no longer exists, an 'external reality' which will never exist, or anything else in between these very broad limits. The only condition is that the model is harmonic and logical. We cannot see the degree of connection with external reality from within the model. This is where the danger originates. Independent thinking will be blocked by the large quantity of information structured harmonically and logically.
Many art films contribute largely to the aggravation of the level of induced schizophrenia (XS1B). At the same time, there are many movies which contribute to the construction of long-range models that stabilize society.
ETA 9: The fundamentalisms of the world we live in
The main fundamentalism is the return to image models, and thus, the refusal of symbolic models. Symbolic models are based on extremely complex functions, which are not easily maintained operational. For a 'regular' brain, the energy consumption is higher for symbolic models than for image models. However, there is a fraction of the population of developed countries working more easily with symbolic models than with image models.
Example: There was a time in the evolution of the brain, when extremely complex image models were built and translated to a symbolic form. It was the time of the great novels (Balzac, Dostoievski etc.). Reading such works was a sign of cultural superiority. These books are not read nowadays. The main reason is the evolution towards symbolic models. The effort of the brain to understand and integrate the use of remote controls, cellphones or text editors is perfectly comparable as intellectual effort with the understanding of the great works of universal literature.
There are too many who have difficulties to operate symbolic models. There is a fraction of the population who refuses symbolic models; this fraction seems to be increasing.
Example: Microprocessors (the central part of a computer) have been invented in USA. At that time there was a tendency all over the world to produce or reproduce such microprocessors. The first microprocessor was called 8080. It was upgraded to 80286. These microprocessors were reproduced in Europe, former USSR and Japan. 80386 followed, which was reproduced with great difficulties, but starting with 80486 the tendency to reproduce such devices was extremely low. Presently there are two families of microprocessors, both designed and produced in USA. This is interpreted by MDT as a danger of a break between the most advanced in the domain of symbolic models, and the slighly less advanced ones (make your own comparison with the automobile industry). Even the advanced cultural zones (Europe, Russia, Japan) make big efforts to keep the contact with the most advanced (USA), but the danger of a break exists here as well.
The fundamentalist reactions of the individuals, nations or even cultural zones are a great danger for human civilisation. If the fraction of fundamentalists will increase too much, then, at the limit, two things might happen:
