Reviews should answer the questions "Who would like this game?" and "Who wouldn't like this game?" instead of stamping a big universal number on it for everybody.
I hate reviews for saying "wah wah wah, it didn't change" when a retro game comes out. It's like they missed the point entirely. Mega Man 9 got bad reviews saying it was too hard. They were basically penalizing a game for doing exactly what it was trying to do (like giving a black and white film a bad review for lacking color). PlayStation Official Magazine UK only reviewed the PS3 version, and gave it a 50, its lowest score, pulling the average down for that version, hahaha. (Mega Man 9 averaged 83 on Wii, 82 on XBox 360, and 77 on PS3.) They had this wisdom to say about the game: "Great stuff for masochists who think progress ended with 8-bit gaming - not so much if you're looking to have fun." How can somebody be so anti-retro and then review a retro game and troll its fans? That's really unprofessional.
Where's a film reviewer who gives every sci-fi/military epic action blockbuster a 9/10 review and then trolls fans of romantic comedies and art-films? They'd be laughed out of film criticism, but they're more than welcome in game criticism.
