Greyvenn, there's little in common with Black Jack other than the profession and the critique of it, approached in a very different way.
I read this a few years ago and think about it a lot.
Many in the US want a different health care system, and certainly, it should be improved. But let's look at how things are from the inside in other places before we idealize them. Japan's problems, featured prominently in this, shouldn't be ignored. I've read articles backing some of the content up and others that add to the mess. Some are because of the mix of system + culture but there is probably a bit of this in similar systems around the world. Unfortunately I can't help but feel that Japan has a monster that can't be tamed.
Not all was critical of the system, though, and there is social commentary.
Some chapters packed a lot of punch with hammy fists, but that's just a matter of taste. It was a bit much for me. Also, the art is rather unpleasant but the artist isn't terrible. I'd be hesitant to recommend because of these things but I'd also like if more people read this.
