Actually, last year after several games had reviews that (essentially) said "The Wii version in this series is the best version so far" and still gave the game 20% to 25% lower scores than they gave the Gamecube version many people started to question the review system.
Certainly, many people did hype Mario Galaxy because of the high review score but a lot of these people started to question reviews after we saw several games in a row get reviews which were close to being the highest reviewed games of all time.
Grand Theft Auto 4 really drove the debate further than any other release primarily because of how many perfect scores it got, the many bugs and flaws it has, several people stating that it was a worse game than Grand Theft Auto: San Andreas, and reviewers admitting that they only played it for a couple of hours before reviewing it.
