The entire series is very entertaining to someone who knows very little about medicine, but if you know a lot about science and doctor stuff, then you may think it's ridiculous since there are a lot of supernatural diseases and made up cures, but still, I believe you can enjoy it. If you're unfamiliar with blackjack, this OVA is a good introduction. It has a very serious, dark art style. Each episode left me feeling something, and I don't think I was bored at all. Personally, I had a great time watching this OVA series of Black Jack. This may be the best so far.
