A brilliant movie made by a brilliant director with a lead character who looks like the real guy. This is a movie about Oppenheimer and not necessarily the making of the bomb. If you are not into biographies this may not be for you. It is three hours long but moves at a steady pace. Imax is the best format to view it in, however if jarring images give you motion sickness a 35 mm format maybe better for you. Frankly, adding the sex scenes were unnecessary and the movie would be better off without them. A must see movie for sure
