Vikram Seth’s huge 1993 book (more than 1300 pages of text; the novel is one of the largest ever written in English) told an intertwined story and touched upon themes like the war between modernity and traditions, family values, familial oppression, generational conflict, prejudice based on religion, among more.
The trailer raises the familiar (to those who know the original story) thematic beats from the book.
For now, it appears the creators are doing their best to actually be true to the essence of Vikram Seth’s book.
