Will MSG improve taste of a food for someone who dislikes the food itself or will it make it worse?

Let's consider a situation where someone dislikes a taste of, let's say, broccoli (or some other food), and MSG is added to that product during the cooking process to improve the taste. Will the taste actually become more pleasant for the person who dislikes broccoli, or will it make the taste even more unbearable (by making it more pronounced)?
