So long as it doesn’t become a pile-on, which it had turned into on reddit, which is why I backed the moderation on r/startrek. Criticism is fine, but when it drowns out everything else, that becomes a poor experience for people who come to discuss a show they like. If you don’t like it, it’s fine to list your criticisms or back those who already have, but if somebody has already talked about those criticisms, nobody wants to hear people repeating the same tired whines over and over. Maybe find a better way to pass your time than dwelling on what you don’t like.
