Excessive positivity in art/game/movie/book/music reviews is an issue even with non-compromised actual-customer reviews. If giving a quantifiable rating (rather than binary), very few people are willing to give a score that's even 50% of the total even if their written review totally pans the piece. Positivity-bloat also occurs with binary yes/no reviewing, but to a much lesser degree. For some reason this doesn't apply to eg. non-book/movie/music/etc. Amazon purchases though - people are willing to call garbage garbage there. Perhaps the greater the real-world utility of a purchase, the more picky people are about it? Or that only fans are willing to purchase art in the first place, much less review it at all, and so fewer who are likely to criticize ever encounter it?
