It is as different as dropping a stone is not physics. One drops a stone and it follows the laws physics predicts, and with physics you can make more accurate predictions of complex systems. The laws would still be there without physics, but our tools and capability to manipulate them would be greatly diminished. It is actually a bit intellectually lazy to use literary critical theory To critique things outside literature, because it is obvious it has no explanatory power outside the subjective reading of a book.
