Have you ever seen a film and found something just a bit distasteful about the way female actor came across but you couldn’t quite point to exactly why it didn’t sit right? And, maybe others have pointed out that the main female character have been treated very well because they ended up saving the day, so what are you complaining about? There’s more to a film than the simply action that takes place and who is on screen. It’s a visual art form and we’re all trained in the visual language of cinema from the moment we start watching films. By ‘visual language’ we mean the way people are photographed in order to convey meaning beyond what they say or do. Someone shown in the frame as towering above another person is often the one with the power for example.
A piece of art’s problematic-ness is subjective to the viewer who consumes the art; there is no definite arbiter--or way of deciding--just what kinds of art are inherently, objectively problematic. Only the individual can deem something to be problematic. If certain individuals agree with others, a mass of individuals with like-minds (and nuanced values) come together, then we have a basic form of society. Some things register as problematic because it goes against culture--or the ideas of a particular social group. To suggest that something is problematic because society or culture deems it so would be like suggesting that something is okay just because certain cultures deem it to be so, but I digress.
