A strange and unnerving film, Nightwish moves among horror movie conventions the way The Player moves among genres. Never quite comprehensible, the movie follows its own associative logic while pretending to become, at various times, an alien invasion film, a mad scientist film, a ghost story, a beast-from--beyond-perhaps-it's-Satan-himself movie, and uncountable others. The acting is quirkily good, the writing witty, and the off-balance nature of the scenes allow the film to move between eeriness, gross-out horror, humor and an even odder element of eroticism--the latter supplied mostly by the lovely Alisha Das, whose character at times seems to treat the proceedings like an especially elaborate session of unnatural foreplay.
