Jokes on them, I never look at 5 or 1 star reviews. By convention I think rating systems are fundamentally flawed in that they are anything but a ubiquitous concept from person to person. Shit, I bet half of the hacker news crowd thinks anything less than an A is a failing grade. The people struggling to piece together how they feel about something in a binary construct generally have the most insightful comments. Kinda like the students who got a couple bad grades in college probably had more interesting lives. ;)
