Shyamalan produces this first instalment of his "Night Chronicles" and surprisingly creates an entertaining, if uninspired, horror tale. After a truly engaging Hitchcockian first half the film unfortunately chooses to go down the familiar path of every silly supernatural horror film ever made and pick off its characters one by one only to build up towards a hammy revelation which doesn't really make sense.
It's a shame because Devil really didn't need to be a supernatural horror. Had it stuck with its original premise and gone for a more Speed/Phone Booth-style thriller it could have been a genuinely tense and clever film. Alas, Shyamalan's head-explodingly naive religious message and childish take on the horror genre boils down an otherwise decent outing to a very watchable but flawed first attempt. One hopes the silliness is either kept quiet or full blown to its maximum in further instalments.
