Maybe we need to define "bad," because I would argue an enjoyable movie is good. Movies don't need to be avant garde to be good. They just need to be entertaining.
I wish this were true, but the critics as a polity just don't have a sophisticated palate. Many individual critics much like many general audience members do, I'm sure.
This sounds appealingly highbrow, but it's not particularly accurate in my experience. I think the critics often get into their own bizarre headspace that nobody else cares about.
