Not really. It's like the 10/10 scores or 5 stars, They all have reasons behind them.
Metacritic rounds all the critics scores up to make one, definite score and gaming magazine (I'm taking the Official Nintendo Magazine as an example) go by this.

0-19% = Unplayable
20-49% = Poor
50-69% = Average
70-84% = Good
85-89% = Excellent
90+% = Outstanding (Gold Award)

It all makes sense.
