Some people legitimately don't enjoy Resident Evil. To them the game isn't a 10/10, or even a 7/10. It might be a 4/10. Regardless of how someone feels, why do they need to give 'excuses'? By using that word, and phrases like 'knocking off points' you're indicating that the game is owed some 10/10 score, and any reviewer that deviates too far from that has some 'splainin to do.
That's ridiculous. Maybe he only thought the game deserved 7/10 because that's how he felt while playing it. Why does he have to have a solid 'criticism' to justify each point lower than 10/10 that he scores the game?
