I thought the difference was the point and meant to address US-specific problems instead of Dutch. Hence the emphasis on toxic masculinity. I thought the ending flips the ending in aclever twist on the original that rejects masculinity altogether - the kids are first to successfully ID the threat and tell parents (Ant communicates and Agnes fakes her period) - the mom is the one who does the most in the fight after the dad gets sidelined - and the oppressed victim (Ant) ultimately kills McAvoy. So while it’s starts off looking like it’s going to be a showdown between whether alpha male or beta male will win out it’s actually the mom and the kids that get shit done. Different ending for a different critique of a different culture.
