The first half especially was incredibly difficult to follow, jumping from scene to scene, past and present. Even the dialogue was difficult to understand as there was moments where I couldn’t even hear what they were saying they were talking too fast. It’s like he was trying to cram in way too much into the 3 hours. Unless you are very into the politics as opposed to the science, you probably won’t enjoy this film. It was confusing, too long with a lack of character development and incoherent story line.
