Modern game journalism isn't journalism whatsoever, it is "PR Cheerleading". All they do is say exactly what the PR companies tell them to say, regurgitating press releases the game companies give to them.
Real game journalism is digging around, talking to inside sources, and writing about stuff the consumer wants to hear about; this may not be what game companies want you to hear.
The large, institutionalized, video game magazines and websites are all a joke nowadays, but there are plenty of independent video game reviewers that have good objective thoughts and opinions.
It's basically one big hype machine driven purely by money.
There's a few good independent reviewers out there that champion integrity such as Total Biscuit, but as a whole I completely agree with this.
Playing a game for the graphics is like watching porn for the story.
