The most overrated metric in entertainment is erratic, reductive, and easily hacked — and yet has Hollywood in its grip.
I honestly can't even remember the last time I used Rotten Tomatoes. From its inception, it was always somewhat of a flawed concept in that it wouldn't tell you how good a movie was, but how favorable it would be to general audiences. If 100% of reviewers gave it a 7/10, it would still be "100% fresh."
I had heard that studios would only invite positive reviewers to early releases, and I had heard studios were gaming the Rotten Tomatoes reviews; so I'm not entirely surprised, but I am a little surprised to see an article about it.
My personal recommendation would be to find a reviewer/ critic who usually has similar tastes as yourself and follow them over the use of Rotten Tomatoes (though if I'm being honest, I've been checking those reviews less often too).
