Who doesn't enjoy seeing evil Nazi's beaten to a pulp, torn limb from limb, and generally getting what they deserve? (Answer: other Nazis). Director Jalmari Helander dedicates Sisu to the art of killing goose-stepping fascists, pitting the despicable jack-booted German's against Aatami (Jorma Tommila), a hard-as-nails Finnish commando who doesn't know the meaning of the word 'quit'. After Aatami strikes gold in the wilds of Finland, he makes his way back to civilisation to cash in his hoard, but crosses paths with a Nazi platoon - and we all know that Nazis like to steal gold!!
However, trying to take Aatami's treasure proves to be a big mistake: no matter what the German's do to him, he simply won't give up until he has gold back and every last Nazi is dead. The fact that the Finnish soldier is so indestructible takes some swallowing, until it becomes clear that his nickname - The Immortal - is to be taken at face value: this bloke has more lives than a cat. Once you wrap your head around the fact that Aatami simply does not die, the film becomes all the more fun, as the enemy come to realise that taking an immortal's hard-earned riches is an even dumber move than nicking a leprechaun's pot of gold.
In terms of style, the film is very Tarantino-esque, split into 6 chapters, each introduced with a big bold title; the violence is graphic, with lots of blood and guts. There's even a group of female Finnish POWs who lend Aatami a hand in killing the baddies - and there's nowt more Tarantino than a gang of women unloading machine guns into a truck of Nazis. The ending takes the craziness up to eleven as the nastiest Nazi, Bruno (Aksel Hennie), makes his escape on a plane, unaware the Aatami has hitched a ride. The action ends with a bang for both Bruno and Aatami, but only one of them is immortal...
One might argue that the plot is slight, and the film derivative in terms of execution, but if you're after a bit of mindlessly violent popcorn entertainment and found John Wick 4 needlessly overblown and overlong, this one should do the trick: it clocks in at a far more reasonable ninety-one minutes.
