If you think bad reviews don't get some massive backlash go look up some Assassin's Creed reviews when the crappy scores were just starting to come in. The backlash was a lot more harsh. http://xbox360.ign.com/articles/834/834676p4.html The first 1000 or so responses are a lot of swearing and threatening and cries of OMFG BIAS.
The only time it's really worth pointing out is when there's an obvious bias or someone is crapping all over a game just for some cheap and easy page hits. Even then it's fun like the "Sponsored by Sony" and "alliwantforxmasisapsp" fiascoes.
But I hope fans of X console or Y game never lighten up, I hope they continue to treat it like life or death. The joy of any console war is saying intentionally inflammatory stuff to get the console warriors in a typing, frothing frenzy. Sit back, relax, take a deep breath, type out something inflammatory and (sometimes) totally off base and enjoy watching socially retarded virgins with FAAAAR too much emotion investment in a piece of electronics explode in a furious rage.
Obviously I don't throw rocks at the bee hive on this site as I don't want to get banned and I like it here, but you have to be zen about these things. This is one of the few places on the internet where discussion is kept somewhat civil, and for that reason (and others) VG Chartz worth preserving.
