In a word – engrossing. Despite a few very minor flaws, namely, moments where you might think 'Would X really do/say that?', this series is well worth your time if you're after something entertaining but not shallow. The characters are interesting and well-acted, particularly Beth Harmon (both younger and older). The story is paced perfectly for me. None of its seven episodes drag, nor do they rush. Well-planned scenes, excellent dialogue, and also very nice to look at. A series I won't forget.
