I see a lot of movies in the theater. Movies like Baywatch and Emoji Movie were awful on any scale, and rotten tomato ratings will keep you away.
This whole discussion is a distraction from the larger problem -- studios are slinging out shit sandwiches as feature films. I should be getting a better film experience in a theater than on a made for Netflix movie, but I frequently don't.
This is also why I dislike Netflix's rating system. There's two axis by which it's measuring (how good the movie is, and how well it matches your interests), and turning a 4 level rating that already combined those nuances into an 8 level aggregate rating and then altering that score based on similar interests lead to quite a bit of confusion as to why something was rated the way it was. Then they doubled down and made it worse by reducing the source data rating to 2 levels and increasing the aggregated output to 100 levels. :/ The only upside is that they are able to throw some interesting compute power and algorithms and/or machine learning at it to generate some good suggestions occasionally.
But that doesn't mean it's useless to look at ratings. It's just for deciding between "I guess why not" and "naw, I'd rather play a good game or something".
