Art or garbage, the answer lies in the eye of the beholder.
However, I'm relatively forgiving when it comes to these type of films.
As Michelangelo Antonioni said:
"I do not believe images need to make sense or be explained."
To me art is all about the feeling.
And as one viewer once said:
"When I've seen something that has affected me but I just can't put it in words,
I know I've seen something special."
What's in a good film? You may love it; you may hate it. But let him who is not a ghost dare say that he has felt nothing.
