So I just found out this video exists: an interview of the filmmakers of Life On Our Planet, released a month ago (so by this time, the show has been around for 8 months).

In the interview, the filmmakers state that they believe their science is great (which as most of you know, is false) due to the 200 paleontologists involved in the show.
At about 1:19, one of the filmmakers mentions the paleontologists changing the number of toes for an animal, basically questioning and mocking the science guys who were involved. This is pretty unprofessional and goes to show how unserious they were about scientific accuracy.
They also said they wanted the animals to look “cool”, which is probably where the modifying of animal designs to make them look more appealing came from. Even though as Prehistoric Planet has shown, accurate reconstructions are naturally cool.
Near the end, they talk a little bit about the second season of LOOP, and say that they are going to have “even more fun” with it. Needless to say, LOOP 2 will probably be as mid as the first season.
