Book recommendation - Kissinger and politics of his time

Hi, I'm amateur, but interested in history. I'm trying to catch up on XX century (now watching The Vietnam War) and one of the more intriguing people is H. Kissinger. I know he had a large impact on the world, but lately I just see heavy critisim of his policies and ideas (e.g. John Oliver's jokes).

I wanted to ask for a good book recommnedation (or documentary) that would explain what he did wrong (and what he did well). I bought years ago his book "Diplomacy" in some supermarket, but I'm worried that it's not a good starter point to learn about something I have no real knowledge about - his own book will probably set me on really subjective path.

I'm interested in either something about Kissinger himself, but maybe more about the general world politics of his time. I would appreciate any recommendation (if book would be popular enough to be translated Polish that would be a plus, but not requirement) :)
