I did something I almost never do and turned off the sequel which just felt so egregious in its cartoonishness (as I expected from the dumb trailer where Benicio fires his handgun like a machine gun an unnecessary amount of times into a target) so I can't comment on its overall merit. I also can't say I entered this impartial though, as the first film had one of the most disappointing third acts I've ever seen, to the point where it destroyed the value for me in the excellent first two thirds.
Sicario embraced the grey world of political macrosystems better than any film in recent memory. By focusing on the fish-out-of-water individual in Blunt, we got to see her journey when exposed to the complex world of ethical compromise, contrasting nicely with a desensitized Brolin, and the exploration of her movement through this shady milieu was constantly exhilarating as if we are being sucked into a black hole of brutal truth that we don't want to swallow either, the risk of doing so in straying too far from the morals we hold dear. Del Toro as the mysterious wild card who is detached enough to play by the rules but with an obscure stake that emotionally grounds him to provide just enough empathy is perfect as is. He stands at a cautious distance while prioritizing his own mission: an enigma that retains a glimpse of humanity (ironically as the most directly violent vessel) between Blunt and Brolin, literally becoming the grey hazy center of this complex work.
So it was to my complete surprise and immense frustration when the narrative completely shifts to give us a left field micro-ending to Del Toro's mission
The transformation from a parallel macro-exploitation/micro-existentially shattering tale of a person upended from their coddled-reality and forcible stripped of their protective facades to meet that macro-reality... into a micro-revenge story(?!) is just sloppy writing, and completely unearned. Del Toro's character was drawn to be in a limbo, like a dark twist on Sisyphus' absurdist existentialism, just going along on a mission that may never end for a purpose that gets muddled in the chaos of moral ambiguity, but here he is given an arc, and it's the end of a long (twenty years or something) arc, going right to the source of the family who killed his. Why am I supposed to care? Who are these villains to me? Del Toro has delivered a phenomenal performance in embodying that grey space and now we are supposed to blindly support the narrative detour as if he's been an empathetic surrogate all along. Yeah, the way he kills the family members off in front of the guy is a creative style of comeuppance I guess, but this felt like a great movie was abandoned in favor of the end of another which had no business being there. I remember leaving the theatre feeling offended at what was done to the audience, and whoever decided to take the story in this direction must have been so set on their own genius idea of watching Del Toro kill off the children of a drug lord in front of him that they decided to include it at all costs, and a huge cost this was.
In talking with people for years after this came out, I've felt alone in how much this bothered me, but it felt disrespectful, self-gratifying and paradoxical by taking a challenging, vague, expansive idea on how moral ambivalence coats the systems that affect us all, and threw it in the trash for an easy, specific, contrived scene that was just 2 kewlll to leave behind. I'd love to hear a defense of it and change my mind, because I desperately want to love this movie for so many reasons that click with my own worldview, but I begrudgingly cannot overcome this chip and feel nothing but animosity towards the cohesive whole.
