@JLNobody,
I was too brief in assessing Braque's work and, in any case, I only find his early fauve work which he tried to suppress as being too close to "prettiness" in comparison to the other painters in the genre. I think I got the impression that he started painting for an audience when he became repetitious but it's, of course, intuition just as some art historians and critics have reached the same conclusion. Art can run the range of objective, to subjective, to entirely abstract (no discernable object or subject) and Pollock falls into the latter category. There are Pollock earlier paintings where he utilized negative space and then there was a resemblance to Krasner's work. Ed Harris referred to that in his film even if it was somewhat subtle.
I do see background and foreground in Pollock's work and it can be very pronounced as his later work which the critics didn't take as much of a shine to. I never found that he, in effect, every tried to fill in all negative space -- it existed mysteriously in the depth of the painting, but, once again, can barely be seen in small reproductions. We're back to the comparison of seeing a film in IMAX against seeing it on a small computer screen. The paintings are almost impossible to reproduce as all the textural motion become obscured in shrinking it down.
I think another problem in going by the film is that all the paintings were actually created in the studio's art department and it was rather too obvious. Although his technique and color-ways are not that hard to ape, there's an almost metaphysical power to his really great paintings that cannot be reached by any attempt to recreate them. As the artists who did the fake Pollocks didn't really try to literally copy any one masterpiece, they became set design.
