The story is pretty heavy drama though. However, it builds up really well from start to finish. Draws you into the movie as you go along. Got me hooked throughout. Intrigue after intrigue. Mystery after mystery as it slowly unravels towards the end.
Added to all of that, there were very impressive performances from Bradley Cooper, Cate Blanchett, Rooney Mara, Richard Jenkins, and many more established actors. Overall, it is a good movie. A superb slow burn of a film.
