Maybe this is the wrong place to talk about this because I'm not pursuing a discussion about spoilers, but the only worthwhile film-specific discussions on the forum seem to happen in this area.
I loved this film upon first viewing, and am generally immune to the "poverty porn" criticism, because I think filmmakers can tackle poverty in honest, humble ways even if they aren't poor themselves. (And since they're making films, they are destined to have some level of privilege over their subjects in these cases.) Now, Letterboxd is not the home to the world's finest criticism (what website is?), but I also think you can find some good stuff if you spend a little time on the site. Several negative, but decent reviews have this pegged as exploitative of the real-life nomads, and find a rich woman such as Frances McDormand portraying one of them as vain. There were some assertions I came across that in particular scenes, the people didn't even know McDormand was an actual famous actor, and that the power dynamics at play made mockeries of the non-professional actors and their stories.
The film came off as genuine, well-researched, and empathetic in my point of view. I know the answer is generally to use your two eyes, trust what you see and know, but I find that can lead to myopia. What do you all make of the idea that Nomadland is a problematic, exploitative, bourgeois piece of filmmaking? (TBH, also hoping oldkid will kick in some wisdom, as he's worked with the homeless, which I get are not necessarily the same thing here, but I think at least in the same ballpark.)
