What is the word, a noun or an adjective that describes majority of comments, on an article for example, as “useless” compared to just one brilliant comment. “Useless” comments are dull, idiotic, stupid, ignorant, nonsense, etc. The word Garbage would be accurate, but it is insulting. The word should not insult anyone. The point of that word is to emphasize the opposing brilliance of one comment compared to 100 of others.
Example sentence:
"Most of these comments are ________, but a few are brilliant."
