Regardless of whether it is a book, movie, musical album, or videogame there are a lot of creative-entertainment products that are produced with little intention of suiting the needs of the snobby-elitist. With the exception of videogames, most professional reviewers take this into consideration and the approach they take with their review is better suited to the product that is produced.
Beyond this, outside of videogame reviews most reviewers actually use the whole review scale to represent the quality of the product they’re reviewing to make the review more meaningful. If you regularly read movie or book reviews that are based on a 5 star scale you get the impression that 1 star is bad, 2 stars is below average, 3 stars is average, 4 stars is good, and 5 stars is great; but in the videogame review scale 3 and below would be considered bad, 4 is average and 5 is the score that any game worth playing would get. While many movie or book reviewers are abstracted from the need to appeal to publishers or movies studios because they work for a newspaper or magazine that has a variety of advertisers, the typical videogame reviewer is (entirely) in the pocket of the videogame industry and rarely has the guts to give a score that is below 60% to any game an advertiser is pushing; many Wii games (like Just Dance) are not really hurt by this because they're not major games for the publisher and are not pushed hard.
