According to Comolli and Narboni:

Accordingly, films can be classified in terms of whether this task is accomplished or not.

This brings out the following categories:

A)Films which are imbued through and through with the dominant ideology in pure and unadulterated form, and give no indication that they are even aware of it. B) Films which ATTACK their ideological assimiliation on two fronts.

C)Films which work "against the grain" insofar as:

D) Films which have an explicitly political content, but whose form and structure adhere to the traditional way of depicting reality. E) Films which seem at first sight to belong within the ideology and be under its sway, but which turn out to be so only in an ambiguous manner.

The other "categories" are really not categories as much as they are discussions of particular groups or genres of films.
