"Luckily", Amazon fixed the glitch by having the "star rating" consist of an "intelligent" summary of the reviews instead of the average, which means that there are products with 3.5+ stars despite having 50%+ 1-star reviews and very few 5-stars. The top review they show is also a paid ("free product") review praising it with a lot of text, nicely pushing all the 1-star ones out of view. It was a HP printer, too.
