Apple executives definitely sabotaged this show through executive meddling after S1
Now for context, S2 of PhP was amazing, however, compared to S1 there were noticeable issues, like shorter episodes compared to S1, questionable moments in the animation and structure of the episodes (i.e. Shamosuchus, the last episode being called North America instead of a specific biome like the others), but all around, S2 manages to make it work.
S3, while great in its own right, has the most glaring symptoms of executive meddling. Not only with issues like the lack of scientific names for the mammals compared to the non-avian dinosaurs due to the executives forcing the show to “dumb it down” to make it more palatable to casual viewers in their eyes, but also with how they treated the show’s staff and the fact that the soundtrack for S3 still hasn’t been released despite it being over 7 months since its premiere.
Now I get that this was an expensive show to make, however with all the background executive decisions that affected S2 and S3 especially and the show’s future looking increasingly grim with so many ideas that were forced to be left on the cutting room floor and ideas for future seasons that may now never come to pass, I can’t help but come to this conclusion.
