Why read this explainer

Treat There Will Be Blood as a loose adaptation centered on Plainview. Its family and religious confrontations do not transfer the full labor and political world of Sinclair's novel.

PlotGeeks note

The narrower family and religious confrontations concentrate the film on Plainview's control. Selecting that conflict changes the balance of a source with a wider labor and political world.
