Honnestly I was a little bit disapointed cause when I went to see it to the movie theater, I was in the mood for a scary movie. Like typical horror stuff. There is some "scary" passages, but it's no It. So don't expect to be full on frightened or to have big jump scares.
However I think it is a movie worth checking out. The acting is on point, the images are vibrant, overall greatly directed. Obviously the movie is a big metaphor, but I went to see it completely blind and I understood pretty easily what it was all about. I'm kind of surprised by the score on IMDB because it has a 83% rating on Rotten Tomatoes and I just heard nice things about this movie beforehand. It brought a tear to my eye even though I am not in the same situation as the protagonist.
Also, the argument of "but what about the exploited workers in the fields ?" is one of the weakest that's always thrown around. Do they realy think that everyone working for the meat industry are all treated fairly ? All those fields of corn/soy that are used to feed the livestock, guess what, they also need workers.
Also, this is indeed not even an unpopular opinion. Vegans/vegetarians are all around some of the most hated groups of individuals. Source : https://journals.sagepub.com/doi/abs/10.1177/1368430215618253
