“What Lies Below” (** out of four) was a muddled psychodramatic thriller about a young teenager (Emma Horvath) who returns home to find that her dedicated mother (Mena Suvari) has a new boyfriend (Trey Tucker): at first, it seems like he has it all but the daughter soon begins to discover he’s an otherworldly alien who plans to divide them apart and kill them. Film begins passably but then becomes unnecessarily unpleasant with sci/fi touches that are abitrary and don’t help film from going nowhere in several different directions. Jimmy Jung Lu’s striking cinematography is a definite highlight throughout.
