If you want to know how to evaluate art, you should look into it.
It was a rhetorical question. Art is subjective and there is no real distinction between the "art" loved by small groups of people and the "art" loved by large groups of people. Nor is there is any reason to say that movies loved by small groups of people who have particular definition of what they call "art" are better than "art" in the form of mass marketed action films.
