What would remedy the situation is doing away with the score system. The pure fact that ratings aren't standardised, and subjective, should be sending off alarm bells for any gamer looking for good critic.
I've been watching Zero Punctuation reviews for some time, and sure it's full of fun stuff and overly critical nonsense, but what he does well is discern 'the bad' very well, which is what a lot of reviewers forego these days.
Also, I just love it how there is no scores - just critical analysis, and at the end of it, you can tell if he liked it or not.
Maybe not exactly what everyone else should be doing, but at least he's doing some things right. Just my two cents.
