Too much of what gets called "criticism" comes from people who aren't really qualified to make that criticism, and is expressed in a way that is not civil or objective or relevant, let alone constructive.

Some critics are just sniping at their competition. Many critics are just trying to show off and look smart. Many critics have the crab bucket mentality. A few critics are the kind of people who entertain themselves by pulling the legs off of animals.

That is why we have the word "haters" to describe those kinds of critics. It's a useful word.
