There are two ways to evaluate a perfume. The first is the impression the perfume leaves on you. This is actually what people evaluate as a “good” perfume or a “bad” perfume. It is a completely subjective evaluation and anyone can do it. Then there is actually “evaluating” the perfume, which is something only people who understand perfumes can do. So actually, to call a perfume “good” or “bad,” you need to understand perfumes. If that were not the case, many perfumes from houses like Amouage, Nishane, and Maison Crivelli would be “bad.” Of course, people who have always smelled the same style of perfumes throughout their lives cannot understand a deep, layered perfume, and most of the time those perfumes smell bad to their noses. So if you have a niche perfume and the people around you do not really like it, you may not need to look for a problem in your perfume.
If you give a Ferrari to a Volkswagen driver, they will say that its suspension is stiff and it makes too much noise.
