It is fine that it is subjective, but this is why reviews from a major corporation don’t make any sense. You want reviews from a large number of individuals so that you can get to know some of their taste to see if it is similar to your own. Then you can make a decent guess if you will also find the thing fun.
Not to mention these major review sites rate on a 7-10 scale which is kind of worthless. They are also effectively bribed by game studios so it is actually worse than worthless. It is actively harmful to finding out the truth.

This isn’t that helpful either. I end up getting lost because of all the different opinions. For example Starfield as a recent example, professional reviews are mostly positive but individual opinions are all over the place. I am left confused.
