Metacritic is not a place for complex feelings, in fact, that's expressly against it's design intent. Metacritic exists to summarize review content from multiple sources (including users) in one place, for an at-a-glance take on industry & user sentiment, extracting a rough signal from the noise.
Writing an in depth review on that platform is very likely to be lost in the cacophony of amateur reviewers, and most readers are there just to gage overall sentiment. Anyone looking to be persuaded to try a game is more likely to rely on the descriptions provided by the professional critics.
