The stylishly shot "Devil" unfolds on two narrative levels. First, the film is a whodunnit-style mystery taking place aboard a malfunctioning elevator in a Phildelphia high rise. Second, the film is small-scale, supernatural horror film involving devilish forces. Most of the film takes place on the aforementioned elevator, focusing on its trapped riders.
While the film, as a whole, offers compelling levels of suspense, the former narrative level works better than the latter if only because of its lack of demonic hokum. Altogether, however, the film is an entertaining experience with crisp pacing and a hard-working cast. The end product may rely too much on coincidences and tricks (though that may be the point) to be taken seriously, but the whole pulpy outing is satisfyingly involving.
