So one thing I also noticed was that each animal had a dramatic mini-story along with it, like the camera crew caught each one at the very beginning of its intrepid (but really routine) adventure to try to fuck or kill something.
It's likely that the footage is spun and edited to fit a particular exciting narrative, and although it's "unnatural" similar to your concern about the overall sensationalism, I don't actually have a problem with it. You can't deny that the storytelling thing that they're doing is really well done. It's gripping, beautiful, funny, and not always predictable from the average Netflix viewer's perspective.
If you're a big nature documentary buff or something, I guess there's a lot of cringe-worthy material here, but it's clearly not an academic work. To someone who just generally loves the idea of sloths heroically crossing rivers just to get it on, it's amazing!
