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.
High Octane Nightmare Fuel: The "spirits" sequences, all the religious chantings sequences mixed with Lady Aoi's torments and Lady Rokujo's nightmare.
Marty Stu: Genji: He's handsome, polite, educated, writes poetry, plays flute, can dance, can ride a horse and fight with a sword!
Values Dissonance: The whole lifestyle of the prince would be considered outrageous on actual days, but back then, were expected as part of a noble's life. Genji, therefore, exaggerates even for that time standards and some of his enemies try to use this against him.
Wangst: Genji whines, gets depressed and cries A LOT.
