Reviewers should be able to discuss whether work is good even if it meets standards of technical rigor.
I may disagree with it, but there was a well-made video about the problem of films that are good enough.
Now it's easier than ever to find old reviews, and determine if a critic went against a later consensus.
Obviously critics could still good points against something is unpopular, but in favor of something that is despised.
Critics are not a hivemind. They may disagree with one another, and an individual critic might not be the one who failed to appreciate a classic.
Does AO Scott say that Art sand Entertainment need to be "intellectual" to be great?
I'll disagree here since I often find it worth learning from critics who have lengthy careers.
They will experience movies quite differently than someone who doesn't know how derivative a particular work is.
Sometimes they'll be looking for weird stuff, but there are conventional movies that got good reviews.
