Loved the choice of actors and how they weaved the story with some witty but thought-provoking dialogue. I immediately went and bought the book afterwards - always wanted to but then the movie made me decide 100% I'd love it. I'll read it first before I can comment on how much of Don DeLillo's storyline was kept in the movie and if it was a good portrayal. Either way, I liked it - don't think many people understand the metaphors and intelligence of the storyline so it might not be everyone's cup of tea if they like surface-level comedy without thinking being involved.
