Kurzgesagt has a history of taking something overly complicated and simplifying it to the point where it looses it's meaning and slips into fantasy-land. With this video, it bridges too many concepts and strings them together, until it becomes unsure what the actual path is.

It does handle a more complex occurrence, so It tries, but it loses it's momentum as it gets going because it consists of too many gaps in facts to complete a proper narrative.

Each to their own, I thought it was great. It's a small glimpse into the mind bogglingly complexity of biological systems that most people have no idea even exist.

Sure Sure, But I've seen quite a lot on this, and explained in more depth by more educated people in a simpler fashion and using microscopic video.

This guy trys, and the animation is interesting but it's like reading a book with every second page missing. You don't know what you're missing unless you already know it.

Or, in better terms, this is like a book report made about a book he's read lately. I appreciate the study which has gone into it, but it's very paraphrased.... which is sort of his style.

Before I watched this video I had never even heard of the Compliment System before so there is that. I'd be curious to see the more in depth yet simpler version you're talking about.

Bombs in my blood. Great. Now I'll never get past TSA precheck!
