These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Asian Saga
Crowning Moment of Heartwarming: In Shogun, Mariko's letter to Blackthorne after her death, encouraging him to build his boat and to never fear. He, in return, dreams of a beautiful, a perfect ship that will conquer all the seas of the world, and unite England and Japan, and will be named The Lady, in Mariko's honor.
Complete Monster: Most of the books of the Asian Saga heavily feature a Gray and Gray Morality, and the majority of the antagonists are well rounded and semi-sympathetic, but Gorth from Tai-Pan is one of the exceptions, being a brutal sexual sadist who, unlike his father, has no sense of honour whatsoever. Gorth enjoys hurting or assaulting others and clearly enjoys their pain. In order to hurt his enemy of the Struan family, he tries arranging for his son to be drugged and bedded by a prostitute with syphilis which was completely incurable in those days and a very, very horrible way to go.
Foe Yay: Dirk Stuan and Tyler Brock are very obsessed with dominating the other. The start of their enmity was when Struan was a cabin boy on which Brock was a bo'sun, and apparently the latter was very fond of flogging Struan.
Magnificent Bastard: Toranaga in Shogun. Being played by none other than Toshiro Mifune helps a LOT: this video shows some of his finest moments. In particular, the look he gives at 0.17 is one of the best "you do not want to screw with me" looks you'll ever see.
Dirk Struan and Ian Dunross from the other books would fit this, too.
Lord Yoshi (descendent of Toranaga) does pretty well for someone in his twenties, and could rival his ancestor once he's got some more experience. Hakim Gorgon Hakim Khan following the death of his father is well on his way to becoming one.
