The following explanation is probably implied but I still want to mention it: When a movie (or any form of media really) discusses such a polarizing issue like climate change doesn't the rating always lose its meaning? When a film, book, etc. treats a polarizing issue, most people probably abuse ratings as a (binary) vote on whether or not they agree with the narrative. And not whether it's a good movie based on film theory (ie. characters, visuals, story arc, etc.). Does this issue have a name? We see it on HN too, where people use up- and downvotes for agreeing/disagreeing, rather than separating informative, from non-informative comments.
