First off, this was not a good film. Nothing new here at all for anyone who's watched TV like Silicon Valley and other startup related content. The direction is clumsy and flawed and there isn't enough interesting going on to make it worth watching. Of course if you want to learn how Jeff Bezos thinks of himself and his life, by all means watch this movie because it beats spending days reading a book on the topic.
But there is nothing adversarial at all going on here either. In order to become a multi-billionaire and own a monopolistic corporation like Amazon, many people and small businesses have to be hurt along the way, not to mention the environment. What would have made this movie interesting would have been the portrayal of how Bezos personally dealt with issues like overworked employees, the unionization (or attempts) of various warehouse/distro facilities, the lobbying efforts and countless dollars spent buying US government representatives and senators, the foray by Amazon's hosting and data divisions into extra-constitutional government surveillance of Americans by way of taxpayer funded contracts with the Defense Department/Pentagon/NSA, the way Bezos decided how to game a lot of Amazon sellers out of revenue through various algorithmic quackery or straight up ripping off ideas (one wonders if Bezos had any role in the Amazon Basics brand that offers knockoffs of already fine products), etc.
Instead we get a hagiography with a little nod thrown in for his ex-wife. We don't get to learn why he decided to become "buff" or the efforts he is making in biological sciences/cybernetics/etc. To try to live forever, his competition with Elon Musk regarding the aforementioned government contracts, the race to mars, or any of it.
Two word summary of this movie: Pointless Hagiography.
