Why do bother watching nature documentaries? I know they're rubbish and yet each time I'm like "maybe this one won't suck"
Right off the bat it's projecting vicious intent onto nature. Nature isn't just shit that happens, oh no, it's A BRUTAL WAR OF DYNASTIES!!!!1!!! 
"Look at this centipede from the Devonian, but invertebrates wouldn't be the ones to win the game of survival" WHAT DO YOU MEAN? WHAT GAME? INVERTS ARE STILL HERE, THEY'RE THE MOST COMMON AND THRIVING LIFEFORM ON THE PLANET.
And of course the whole thing chooses to fixate on competition and ignore how much of nature revolves around cooperation and symbiosis.
I am begging the media (especially media that sells itself as educational) to stop speaking about nature the same way a 1930s German pseudoscientist would.
The only good nature shows are produced by the BBC, which is generally good outside of news.
Coming soon to BBC: Actually clownfish never change sex that's ridiculous nothing changes sex ever it's simple biology.
Reminds me of a segment from Blue Planet II, where they show a fish that changes gender, but portray it as the most terrifying shit ever, horror music included
I tried watching Nature's Greatest Events last week and it was horrifying. It showed a cuddly polar bear mum and cubs struggling with breaking ice sheets as summer approached in Antarctica. Attenborough remarks how climate change and shrinking ice is making it difficult for polar bears to hunt.
The documentary was shot a decade and a half ago. I hope things aren't much worse them but I felt really really guilty watching that.
