A critic should be objective about objective things: frame rate stability, glitches, loading time, sound quality. A critic should be subjective about subjective things: art style, enjoyment/fun, genre preferences.
If I was a critic I would generally score FPS games lower than average because I don't like FPS. As long as people who read my reviews understood that I don't like FPS then they will be able to contextualise my review.
The problem is when people read a review and don;t understand the tastes and preferences of the reviewer.
