I mean if you can look past the BLATANT bias throughout the entire series, there is a lot of interesting information. You can learn a lot about the meat industry and there is cool technology that helps create good alternatives to meat.
What I disliked:
A large portion of the show is about the meat industry and not the twins or the experiment. The title/thumbnail is essentially clickbait. It felt like the twins were the side story.
Parts of the experiment were not even conducted properly. The arousal testing had 2 variables since the twins chose DIFFERENT porn the second time around. One person vocalized that they loved the second selection way more. People also openly admitted that they did not follow the diets/workouts as they were suppose to. Overall, the "study" wasn't conducted very well & was not a big part of the series.
