Of course, ratings in reviews are subjective. All reviewers are looking at the subject in many different ways, whether it be a television series episode, movie or novel. There are many things in an episode I would look at when I'm reviewing it, and deciding upon the rating. Not only how the story and the characterisation work together, but also how I enjoyed it, and how well its themes show through. In the case of a series like Discovery, how well the episode continues the overall story is also considered.
But these are not the only aspects that are considered. It's also a matter of comparison with other episodes in the series. Sure there are stinker episodes, but I would rather watch Vaunting Ambition, Threshold or Spock's Brain, rather than something like Shades of Grey (which would definitely get a low rating).
