This film is a character study of an alt-right man that's a sexist, gun obessed incel that lives in his mother's basement. He takes life far too seriously and blames everyone else for his failures including left of center politics, women and especially immigrants and minorities.
This movie seems to want to ridicule people that are on the right, or at least trigger them, and vilify them as little better than psychopaths wound up by a ocean of online hatred. When dealing with this thorny subject it would be much better to attempt to analyse why the world has become so polarized, as to why these people blame so many others for their lack of social and economic mobility and how they are so bound up in a internet opinion echo chamber seige mentality of hate. Instead of finger point and laugh and condemn, it's far better to try to understand and discuss.
Even though the movie does not offer any real insights or understanding on a political or social level the acting and direction are all beyond satisfactory. Worth a watch and good for sparking discussion, but I'm not sure what this movie is really trying to achieve, so I feel it's somewhat exploitative. If there was a resolution in which the protagonist was able to come to a new outlook as American History X it would be a more deserving piece of cinema. I worry this work will harden divides instead of soften them.
