This is a documentary that physicists will love, as will others who really love science. It's the kind of film that carefully explains the difference between theoretical and experimental physicists. If that kind of distinction interests you, then you will like the film. A lot of physics jargon is tossed around in this film with no explanation so you need to bring a working knowledge of particle physics if you want to fully understand the discussions. If you don't know what a GeV is and that lack of knowledge is going to bother you, then you will not like this film. If you enjoy an explanation of the opposing physics theories of supersymmetry and the multiverse, then this is your film. Also, if math scares you, there are blackboards and whiteboards full of some of the hairiest equations you're likely to see. If you find such things frightening, just turn away.
However, if you'd like to meet people who have staked 10, 20, 30, even 40 years of their career on the moment when the ATLAS team finally announced "We've got it!", then this film is for you. This film paints an accurate though relatively lightweight picture of the years spent making the world's largest machine, the LHC (Large Hadron Collider), operational and then confirming the existence of the Higgs boson 40 years after it was predicted in theory. It's exciting to see scores of smart people stretching their brains to the limit so that they can understand something truly fundamental about the universe.
Although billions of particles were smashed in the LHC experiments needed to confirm the Higgs, you will mostly see calm scenes of crops growing in the LHC's vicinity. There are no car chases or crashes, no battling giant robots, no aliens. There are just lots of smart people saying highly intelligent things, most of the time. When they drop into small talk or take time out to brew an espresso, it's actually jarring. (At least it was to me.) About the audience: There were about 40 people in the movie showing I attended on a Sunday afternoon. Every single one of them looked like they had an advanced degree in physics or some other hard science. Indeed, that's who this movie is made for.
