The documentary lays out every aspect about what is wrong with the official story about the moonlanding. There is no dramatic music or strange mysteries, so you don't feel manipulated as a viewer. You feel the documentary approaches the subject objectively. It is firstly about how the apollo project didn't go as well as expected, then how it was very hard to get humans to the moon and lastly how the footage on the moon is extremely problematic. Throughout this documentary there are several debunkings of the moon conspiracy theory that the documentary explains are actually false or unlikely.
If the moonlanding was faked, then there are dozens of questions that pop up into your head. This documentary goes into all of them and that's why it's 3,5 hours.
