The plane crash, cleverly edited to look like one seamless take, is reasonably scary – as is Beau Bridges' rendering of the pilot's fatal stroke – and there are effective jolts and edgy passages involving a hungry cougar, a precipitous tumble, and a totally unexpected bear trap. But from Elba's and Winslet's very first tête-à-têtes, with their forced banter as unconvincing as their blatantly foreshadowed romance, the stakes in The Mountain Between Us feel almost ridiculously low.
