you have a point, although there is still a degree of uncertainty
it'd be kind of difficult to get actual ratios of people who disliked it and said something versus people who liked it and said nothing, and I still think that reviewers are too small (and possibly too biased) of a group to truly be used as an idea supporting game quality
that being said, I return to the idea that sonic 4 getting good reviews doesn't really matter in a debate about whether or not it is poopy
