90+ on Metacritic may be what you’re thinking of, those can be more arty films that may or may not appeal to non-critics. 100% on Rotten Tomatoes is usually the opposite, crowd-pleasers that appeal to all audiences. Nothing amazing or groundbreaking, but a movie pretty much anyone will at least enjoy.

Since RT is just saying what percentage of critics thought it was watchable, high RT percentages just indicate universal enjoyment, they don’t say anything about HOW good the reviewer thinks the movie is.
