Metacritic user ratings have literally never mattered and never been an indicator for anything. I'm pretty sure every relatively popular game on it gets "review bombed", because anyone who actually wanted to review it wouldn't review it there. This is non-news.
Doesn't metacritic aggregate reviews from other sources on their review scores as well? I havent really considered any of the big name review places a reasonable source for a long time anyway.....
Everyone expects the next big game every game. How often can a studio really live up to the hype people create?
