Spoiler alert: the grisly horror movie Jigsaw ends with some brains departing a skull, and making tracks for the floor.
To keep your own grey matter where it should be housed, you should only come along should you feel the urge to witness a belated eighth instalment to the Saw franchise.
There hasn't been one of these flicks since 2010. Though a lot has changed in the realm of horror in that time - thanks to the likes of It and Get Out, 2017 is actually the most popular year for the genre in movie history - it is very much business as ooze-ual in the Saw slaughterhouse.
You know the drill here. A movie like Jigsaw is not here to make friends. It is here to make you feel as if you might be about to lose your lunch.
A quartet of young miscreants is being held against their will in an enclosed space, which houses an elaborate maze of pop-up torture chambers, snap-down booby traps and an assortment of all-too-literal dead ends.
As is the one abiding rule in the Saw playbook, contestants in this event have earned their place on the gruesome obstacle course for past sins they are yet to confess.
To make it to the finish line, they might well have to wave goodbye to vital organs, digits, limbs, or a substantial percentage of their lifespan.
Meanwhile, a cabal of clueless cops and forensic morticians wonder aloud if this is all the work of the murderous mastermind Jigsaw, seemingly still hard at work in spite of dying at the end of Saw 3.
If you have taken in all the Saw movies, you've probably given the franchise a leave pass to keep raising and erasing the spectre of Jigsaw (and his spookily soothing voice, courtesy of actor Tobin Bell) as it so sees fit.
So if it's just those ornately designed dicings with death that you've come to see, there will be enough pieces to Jigsaw to keep you enthused, amused and repulsed.
