What Lies Below ★★½

Even if her character as written sorta deserved the ending, Ema Horvath didn’t deserve this script.  This Netflix movie of the weekly top 10 feels like a bizarre mashup of The Stepfather (1987) and Humanoids from the Deep (1980), which is like taking two 2.5 / 5 rated movies and hoping to get a 5 / 5 result.  But that’s not really how the math works.
