The main character is an *******, it's supposed to be a critique of capitalism but other than Ali and #067 everyone in it seems to be in dire straits almost entirely because of their own flaws, which honestly undermines the critique. Besides which, the MC is still kind of an *******. Sure in the games he shows his kind face but in the real world he is, despite his best intentions, just not a good person in any way.
It also goes for facile mass murder, let's be honest, violent death seems to be everything it has going for it. The Ep1 tachi scene is more powerful than the rest of the show put together.
It was basically meant as a vehicle for battle royale and lo and behold we got a big battle royale with the barest social critique. So you know, it's passable mass entertainment which is all it was ever meant to be.
It's not much to write home about. Watch Train to Busan for a more nuanced and just as gory take. Seriously. Much better.
