★★★☆☆ "This is not a good idea." Uttered around the halfway mark by Samuel L. Jackson's nonplussed President William Moore, this neatly summarises the thesis of Jalmari Helander's Big Game (2014), an imperfect but enjoyable mixture of McTiernan-esque violence, Bruckheimer-esque silliness and 1980s-vintage Spielberg kids' adventure. Indeed, Big Game's veering tone often threatens to derail the audience's suspension of disbelief, which is saved, by a thread, by a welcome and surprisingly un-badass turn from Jackson's President Moore and the exceedingly likeable youth, Oskari (Onni Tommila), clearly having a blast playing Potus' diminutive, self-appointed bodyguard.
