“Titanic 666” (*1/2 out of four) was a paltry horror thriller about a crew (Keesha Sharp, Jamie Bamber, Lydia Hearst, and others) aboard the Titanic III who are besieged in the middle of the ocean by dark forces that rise to the surface and threaten everyone on board. Basically a Roger Corman version of “Titanic” but (to put it mildly) these thespians are not up to the level of Leo and Kate and director Nick Lyon is no James Cameron. Cheesy production and feeble writing might make viewers wish this voyage really did hit an iceberg!
