“Havana Darkness” (*1/2 out of four) was a thoroughly routine horror melodrama about three friends (Carolina Ravassa, Guillermo Ivan, Zach Rose) who travel to Havana, Cuba to investigate the origins of a manuscript supposedly written by Ernest Hemingway but find themselves trapped inside an abandoned building and being stalked and killed by a masked murderer who doesn’t want the truth of the manuscript to come out. Cheapjack mishmash of “Saw” and countless other schlock horror movies with the Cuba scenery its only novelty. But film’s ugly cinematography and shoddy lighting renders even this to look dull.
