I made the mistake of casually throwing on the next episode of Primal on my computer while I sat down to eat lunch... Needless to say about 5 minutes to this one in I had to pause it, because jeez this is absolutely disgusting animation... It is however also one of the most powerful pieces of animation and sound design I've seen in ages.
I was getting goosebumps at the end not gonna lie, the roars of the animals along with the brutality of it all really cuts to the bone, so to speak. Tartakovsky is a legend to me so I have some bias, but this is genuinely great unapologetic brutal storytelling the likes of which are so rare nowadays, and that sucks to say.
