The most glaring omission is that it doesn't stop to acknowledge at all the impressive growth that WeWork saw. Yes, there were all kinds of problems with the way they managed their growth, and some major challenges with the basic fundamentals of their model. But there were many (hundreds of thousands?) of real users in many cities paying them money for office space. To just write that off as "lol, you re-invented the office" is a little ridiculous. They made a product people loved, and that IMO genuinely was an order of magnitude better in user experience than most other short-term office space that existed at the time. It saved time on all kinds of things, from basic cleaning, coffee and tea, flexible meeting rooms and private phone booths, and a generally comfortable space to work in. Those are things that have real value to anyone who is busy working on their company and just wants a productive turnkey place to work. It's weird to write all that off as just shallow millenials being too vain to work out of a Regus (which is a company I had never even heard of before the documentary, despite having been in this position of needing a small short-term office space for my startup in the past).
Maybe I'm just a crazy, biased shill and a sucker for any startup story, but IMO it would have been a much better documentary if they delved into this side of the narrative - how did such an out of touch, seemingly crazy person manage to build an actually good product that found quick product market fit in the crowded real estate space?
