Adam Wingard’s Onslaught is aggressively weird and insanely violent, yet still accessible and thoroughly enjoyable—especially for fans of gonzo Grindhouse fare. Oh yes, this is not going to be for everybody. But for those willing to embrace its particular brand of madness, it’s an absolute blast. The film won me over with its pulsating energy, brazen brutality, and wonderfully unhinged sense of style. It’s also a movie that seriously trims the fat, keeping things narratively lean, mean, and moving at a pretty relentless pace. Okay, so maybe the character development is a bit on the thin side (and that’s being generous). But hey, you still root for who you need to root for, and Adria Arjona is pretty badass as the rough-edged ex-sniper mom trying to hold everything together while Terminator-like super-soldiers attempt to murder her and everyone around her. Dan Stevens also deserves a nod for playing the very unrecognizable mad German scientist Dr. Hans Kammler, a wonderfully bizarre character with, among other things, a foot fetish. He’s clearly having a blast with the material - as is the rest of the cast. Everyone is really game here and it’s fun to watch! Perhaps the person having the most fun, though, is whoever was put in charge of the on-set blood. Because yes, there will be blood… and guts… and all manner of body parts splattering across the screen. Did I mention it’s violent? Well, it’s certainly not for the weak of stomach. And thanks to the wonderfully weird stylization and pulsating soundtrack, the whole thing becomes less exhausting than it probably should be - and more of a deliriously entertaining sensory assault. Thematically, however, it’s pretty paper-thin — is there a message here beyond “don’t trust the government?” Not really. And, let’s be honest, super-soldiers have been done to death. But originality isn’t exactly the point. This movie is here to hit the gas, throw a bucket of blood at the screen, and see what happens. And, perhaps most importantly, it’s always entertaining. And sometimes, that’s more than enough.
