I'll second that method. Positive reviews are uninteresting; 1-star reviews reveal whether there really is a problem/deficiency, as usually the complaint is unrelated ("product arrived damaged"), misguided (expectations were bafflingly far from what product is, "this washcloth is a lousy database manager"), or a fluke (50,000 5-star reviews and one "one page was folded, replacement was fast & free").

I directly read 2 star reviews. 1 star reviews are often super biased and pissed. Much like in yelp, it contains things like "The shoes didnt fit" , "The delivery guy was mean" and stuff like that.

Works for Yelp reviews too, after disabling "Yelp Sort".
