In a technical sense you are correct. However if it is still good to a large group then doesn't that make it good? Take a song for example. You don't like it but 10 million do. Is that song good or is it bad? What are the thresholds for good and bad? Isn't something that is successful good by virtue of being successful? Society even has phrases such as "It is so bad it is good" which further complicates these types of discussions, right?
Because it really is subjective and the technical aspects that can be objectively ruled are often times of little importance.
