The problem is that we do not know it could most favorites, most clicks etc. It could also be on specific people which would be really fucked up. These days I trust opencritic way more since they are also very transparent about their systems. But even they they are very close for most games. I just wish metacritic would ignore these obviously click bait scores.
So the unbiased difference is even bigger.
Anyway.. my point remains. Saying that a score based on consensus is wrong is pure denial.
