RT ratings are weird because they don't reflect how
much critics liked a movie, only whether they rated it "positive" or "negative". The movie with the highest rating ever is Paddington 2 - not because any reviewers thought it was the best movie ever, but because nobody hated it. It ranks higher than Citizen Kane, despite many reviewers literally calling that the best movie ever - but at least one reviewer didn't like it. So RT ratings favors inoffensive and uncontroversial movies appealing to the largest possible demographics.
And shows are often reviewed after only a few episodes. Typically two to four episodes are released to reviewers before the premiere, and this is what the review is based on.
So a high rating means most reviewers reacted positively to the first few episodes.
