Would you call this an 'art film'?

… Or maybe it should be called part of the avant-garde genre? What do you think?

The reason I immediately thought of the European "art film" genre is because that 1950s/1960 genre of film that was popularized in Europe was characterized by a lot of symbolism, romance, and some weirdness. I thought this film had pretty much all of that. The only difference is it was a little cruder than "art films" usually are. But that's because of the decade. Art films were popular in the 50s and 60s, when classiness reigned supreme, rather than crudity.

It seems like Faye Dunaway's later years (the mid-1980s to mid 1990s) were dominated by art films. And that makes her resume very interesting. It's one good thing about her being more or less ignored by mainstream Hollywood.

For an American film, it has a distinctly European film flavor.

Please excuse typos/funny wording; I use speech-recognition that doesn't always recognize!
