So the other day I saw Blue Ruin, and it got me thinking about how The Last of Us 2 completely fucked itself over with its whole cycle of violence shit. Blue Ruin has sort of the same basic ideas, even some of the same twists, but it manages to actually be good.
Blue Ruin gets away with its cycle of violence themes because, by the end, the revenge story ends up becoming emotionally hollow and meaningless. In the end, it's just a bunch of people murdering each other over something pointless, but rather than use this as a way to piss off the audience, Blue Ruin opens itself up emotionally. It's downright tragic that events unfolded the way they did, and the movie implies that everything could have easily been avoided. This even affects the protagonist, and as the movie reaches its climax, you get the sense that he realizes that everything has been for nothing but it's far too late to fix it, and he feels compelled to end it. That is a real cycle of violence and how people will endlessly perpetuate it. Where Last of Us 2 fails at this is that it's trying to get the audience to sympathize with a character who outright murders a protagonist from the previous game over a twist that's only introduced to set up conflicts that have nothing to do with the previous game. There's no real way to set up that same moral ambiguity that Blue Ruin sets up, at least not in any smart way (especially since the game has to frame Joel as a psychotic bastard to justify Abby's motivations). Even Blue Ruin gets this right when it's revealed that the guy the protagonist kills wasn't even his parents' murderer and that the real murderer died of cancer years before, showing that the protagonist's quest for revenge was ultimately meaningless and destructive. The twist doesn't come out of nowhere; it's foreshadowed repeatedly throughout the movie, and because revenge is the movie's central theme, it's able to tie that twist into the core of the movie without shitting all over continuity.
It also helps that Blue Ruin was directed and written by someone with actual talent.
