Until some years ago, I‘d just have a glance at the score/stars and make my decision.
By now, if something is rated low but my gut feeling tells me that it could be off, I always do a quick check of reviews, and 90% of the time I go „Okay, it’s the racists again“.
Also: „high critics score, low audience score on Rotten Tomatoes == racist and/or LGBTQ-haters being racist and/or LGBTQ-hating“ is a frighteningly precise heuristic.
