I have no horse in this race but I was active on the wsb and superstonk subreddits to know they didn't present the whole thing. First off I just hate when documentaries and movies like the big short assume that people would lose interest if they explained things like shorting, margin calls or any other things that are central to the story. I don't want a chef or Margot Robbie or some distraction to be fed the critical information that I need for understanding the documentary. Secondly the interviews in this 'documentary' in particular makes Liam Neeson's action scenes look like a one take cinematic masterpiece. They are so chopped up they are the equivalent of a ransom note. Like let the guy speak for a minute would you? Third even though I can't definitively say this documentary is biased to the one side, it sure seemed like they omitted or brushed past lots of relevant details especially surrounding Robinhood and the big banks. I don't know if they interviewed some people to represent the day traders and redditors and they chose the guy who would be a clear opposite in contrast to the Wall Street guys or what but I cringed watching that interview and thought this guy must be hired or the video highly edited.
I don't live in the US and have never participated in anything resembling a stock market and I could clearly see this needed a lot of input before airing. Don't watch this to know about the GameStop saga. The best thing about this documentary is that if you suffer from insomnia this really helps you get some good nap right infront of your tv. It also creates a conducive environment to just leave it on and have sex with your partner. In some ways this documentary is one step backward for documentary film making but one giant leap in therapy.
