I thought it was definitely aimed at the "newbie" crowd who struggles with blowing their entire paychecks and comprehending things like stock indices or CC interest. Yet the following breadcrumbs offer areas for further exploration for the "advanced" MMMer:
1) Tiffany Aliche's concept of Needs, Loves, Likes, and Wants: This is an interesting framework I'm going to explore further. The idea is we routinely sacrifice our needs and loves for the sake of short term dopamine hits from likes and wants. Thus our homes end up full of plastic garbage that we "like" and "want" but for these things we sacrifice our "needs" for financial stability and our "loves" of what we could do with our lives were we not on a consumerism treadmill. I find this paradigm highly motivational. It explains so much.
2) The cinematography is full of passive-aggressive silent facepunches to laugh at, like when the person who struggles with credit card temptations buys a latte at Target and brags about how they only went off-list on a couple of things, or the zoom-ins on the going-broke NFL player's bling and Range Rover, or the look on MMM's face when his couple is proud they got their spending down to a mere $100k/year. The director seems to get our sense of face punching humor at some level. It's too obvious to have happened by chance.
3) The documentary exposes us to a wide range of scenarios, and offers itself as a lesson in how to talk to friends, spouses, or loved ones in each situation. I think we sometimes get super technical and analytical on this forum and become the professors who couldn't successfully teach a classroom of first graders.
a) The broke high-salary / high-spender
b) The emotion-driven impulse spender
c) The "trapped in my dead end job" creative type who isn't into analysis
d) The family who sees spending money as the solution to most problems
4) A chance to reconsider some of the fundamental personal finance concepts we "advanced" mustachians think are too basic for us, such as automation of separate accounts for bills, spending, and savings, elimination of credit cards, budget spreadsheets, cooking, etc. I know I've slipped away from these fundamentals under the assumption that I don't need them anymore, and habit will suffice. But I bet I could squeeze out a couple thousand dollars worth of value by picking these habits back up.
