My take on the movie could be wrong, but it's still interesting to think this stuff could unconsciously seep into the movie.
I like to think this is a well intentioned movie by two Jews who are willing to be self reflective, Howard Ratner isn't really bad dude per se, he has every intention of paying off his debt to Arno and with interest, but in his wheeling and dealing he simply fails to see how he's pissing Phil off, "this is how I win" he says but it's actually how he loses, well intentioned he may he simply lacks the ability to take a look in the mirror and other Jews like Arno have to suffer too because of it.
It's interesting how stereotypical Howard is as a character to some degree but he also feels like a real human being and is still sympathetic, this is a movie interested in reality, the polar opposite of most "Woke" media these days, even walking stereotypes have layers to them, this movie being both willing to acknowledge the stereotypical side while delving into the layers of them is really refreshing.
Of course I could be reading too much into the movie, but eh, I watched another movie just a couple of months ago, 1989's Let It Ride starring Richard Dreyfus, about another Jewish guy who likes to gamble, this time it's betting on horse racing, but that movie is very clearly using gambling as a metaphor for something greater, about faith in God.
I think Uncut Gems is doing something similar, but either way it's simply a well made movie that's worth watching, the tension during certain scenes is so thick you could cut it with a knife.
But I also simply like the fact that Julia is a character who is generally portrayed positively and one point she's wearing a cross, am I reading too much into it? Maybe, but I like to think there's something positive behind that.
