For you and everyone else lurking with similar query: learn theory and be dialectical in your approach.
Still visual media? Learn colour theory, compostition, light etc Then tie that in with theory of media you are analysing and the history of where the art is from and what it what trying to depict, including which classes produced it and which classes' perception it is reflecting.
Same for music, literature, films etc. In doing so you will develop your own tastes and also be better educated in analysis. If you learn enough chances you will produce your own as part of that learning process.
Read broadly. You will likely need to read a bit a about philosophy including marxist critiques on Nietzsche especially when it comes to the arts.
As your knowledge grows it will be easier to learn new stuff building on previous things; learning the interconnectedness not just within the arts but with also outside of the arts (history, geopolitics, philosophy, hard sciences etc) will make it so much easier to learn and enjoy.
