This film is absolutely Art and as are all great films. I tend to seek out good critics as opposed to those who’s opinion I don’t esteem. The NYT has exactly one good film critic and he reviews DVDs mostly of classic films.
Art is in the eye of the beholder. I doubt it’s art but you think it is so we’ll leave it at that. Maybe it is. As I said, Che’s photograph is art as well. “Birth of a nation” is considered art by some (as is “Gone with the wind”).
Like you I too look at multiple sources for a film review. I go to Rottentomatoes which I’m sure you have heard of and read a variety of reviews.
All I am saying is that often I will read reviews from those who did not like the film to see what their complaints are. There is an awful lot of wisdom and insight to be found in listening to a personals critiques - whether it be film or politics or relationships.
