Why read this explainer

Compare Crichton's unstable ecosystem with the film's capture operation and San Diego sequence. Sarah and Ian's family responsibilities also give the expedition a different human structure.

PlotGeeks note

Sarah and Ian's family responsibilities change the human stakes of the expedition. InGen's capture operation and the San Diego sequence organize a conflict different from the novel's scientific inquiry.
