I’ll say this about siblings Anouk Whissell and Yoann-Karl Whissell, of the directing team RKSS. They make uncompromising and unrelenting films. This is true of their debut, Summer of 84, and it’s very much true of their latest release, Wake Up. Their newest feature pits Gen Z environmental activists against a brutal security guard. The result is a bloody slasher set in a mega furniture store.

The siblings, working with a script penned by Alberto Marini and Martin Soudan, waste very little time getting to the mayhem and bloodshed. As the film opens, the activists lurk around the store, donning colorful animal masks, a striking visual throughout most of the lean runtime. They film each other defacing the store with bags of animal blood and shooting paintballs all over the place. Armed with smartphones, they message about deforestation and loss of animal habit. This is a worthy cause, but well, the group comes across as rather preachy and annoying. Various members accuse each other of not going far enough, not being enough of an activist.

Their hijinks don’t last too long, however, before they run into the hulking figure that is night shift security guard Kevin (Turlough Convery). Oh, and Kevin is a primitive hunting fanatic. How convenient! He’s crafted all kinds of weapons that he employs to pick off the activists one by one, in rather gory fashion. Kevin, who’s berated by his boss and whose only real friend is his brother and co-worker Jack (Aidan O’Hare), is nothing to the rest of society. As a hunter, he’s a punishing force when he takes up arms against the Gen Z activists. Convery is simply imposing on screen.

This film has plenty of carnage, but not a ton of character development. No one among the activist group really stands out, other than maybe newbie Karim (Tom Gould) and ringleader Ethan (Benny O. Arthur), but even those two aren’t given much to do other than try their best to evade Kevin. There are some interesting interactions between Kevin and Jack, but even that’s rather light. This film is more about the kills than anything else, though it does sport plenty of memorable visuals beyond the animal masks. There’s a sequence where Kevin douses them in black-light paint to hunt them in the dark. This looks great.

Though the film features a group of young activists, it doesn’t really have a political message. There is something to be said that these Gen Z activists face off against two working-class security guards who desperately need their jobs, but that’s about it. More than anything, this is like an old-school slasher with a simple premise that’s generally executed well for what it is.

Wake Up has visual flair and plenty of kills. It wastes no time getting down to the bloody nitty gritty of things. Horror fans who dig a straightforward slasher should check this out. It certainly paints the store red.
