@SirTarquin - gosh, I disagree so much!
The Wolf Hall trilogy needed dramatis personae because roughly half of the (historically significant) characters were called Henry or Thomas.
All the Iliad stories (Silence of The Girls, Women Of Troy, Song Of Achilles, A Thousand Ships, The Penelopiad etc) needed to make sure their readers knew which person was aligned with which side.
I also like books like Life Of Pi that present a dichotomy and ask us to choose. I am happy to own that my instinct to to chose the beautiful lie over the terrible truth.
Chopped timeline books like Build Your House Around My Body let complex stories reveal themselves through nuance, overlapping narrative and pacing. To have told the story sequentially would have been to have diminished the narrative arc.
