“The Creature Below” (*1/2 out of four) was a subpar sci/fi horror show about a young scientist (Anna Dawson) who discovers a malevolent entity at the bottom of the ocean which leads to her enacting revenge but later descending into the perils of insanity. One-note story of a sick woman’s lurid descent and revenge goes overboard and is often gross and disgusting. Dawson is OK in an almost unplayable role.
