Magical swords, evil doppelgangers, a sexy black muscle car, an unremarkable final showdown and lots of first-draft dialogue factor into this thankfully brief (about 80 minutes plus end credits) frightfest.
Intriguingly, Jinn makes a plea for understanding and cooperation between Muslims, Jews and Christians. Disappointingly, writer-director Ajmal Zaheer Ahmad does all too good a job burying that message within a blustering supernatural thriller.
Most of the time, this incoherent thriller resembles an overheated trailer for itself: a glaringly rough assembly of ill-staged computer-generated action sequences and portentous moments.
