There’s a flipside too, I don’t know if you’ve ever seen the Zero Punctuation reviews, but at least that guy tries to find faults in games he "reviews", if a bit over-zealously (which adds to the amusement factor though).
I do agree with you to a large extent Ronan, even reviews where they spend a bit of time going over the faults of the game and then still give it a 10/10 baffle me the most. Ultimately though, I don’t think it’s possible to review games objectively, as everybody has different tastes. If you get someone to review a sports games when that person hates them, it’s going to be a more negative review than if it was reviewed by someone who loves them. For the same reason I tend to take a pinch of salt with review scores, because the reviewer who gave the score might have a different taste to me.
