I recently saw “Rampage” from 2009. Its basically a movie where a spree shooter is portrayed as the good guy/anti-hero. Several parts gave me that pit in your stomach, teeth gritting uncomfortable moment. I really hated it. Although I’m not surprised there are sequals I am disappointed and will not be watching them.
The War Zone is a great pick here. Tim Roth’s contributions in this sphere are notable, that was his directorial debut, and before that his acting debut was playing a teenage skinhead in Made in Britain which fits the criteria too.
someone mentioned Michael Haneke elsewhere, Roth is in the english language remake of Funny Games, another film that meets the requirements and one of the the few remakes worth watching, due to it being a) an exact replica of the original but in english and b) having tim roth in it
