TMDB is even less representative than IMDB and Rotten Tomatoes (which already skew older, male and are very American in representation).
It’s fine if you subscribe to a group that aligns with your own views, but don’t take the self-selected non statistically valid outcome as anything but a reflection of the subgroup that subscribes.
Paramount+ on the other hand needs to draw in a large and demographically diverse audience to maintain a subscription base. The episode wasn’t a hit with your niche, but other ones will be. It definitely was a hit in our household.
