I know from first had experience why that difference is, at least in the realm of classical music reviews.
The critics are professionals, the audience is not. The observations of critics are based on years of experience and written for a large audience with their real name associated with the piece.
The audience can (nowadays) vent their options too. Mainly anonymous and for the better part describing their personal feelings about the experience.
Not saying the one is more useful than the other, just that the origins and intentions are completely different. I like the fact I can easily access both, and sometimes even compare the two (Rotten Tomatoes for example). But I do think the two scorings addressing two different issues.
