Adapting a non-fictional book is no easy feat whatsoever. Christopher Nolan could've easily filmed this movie in a linear fashion but brilliantly chooses to intercut scenes between different sub-plots and time periods of Oppenheimer's story. This approach was the best decision for the audience and to cover all the facts in this true story.
This film will be remembered as one of the most important films in this century and will continued to be discussed for many years.
