“Psycho Sister-In-Law” (** out of four) was a synthetic horror thriller about a happily married couple (Haley Downes and Brando Eaton) about to have their first child together when the husband’s father unexpectedly dies and his estranged- and psychotic- sister-in-law (Lydia Hearst) shows up and wants her piece of their estate and also their upcoming child. You can pretty much guess the rest. A movie compendium of thriller cliches and plot points made for those who have basically never watched a thriller before. Cast of decent actors and attractive lighting at least give this a glossy surface but you’ll forget this pretty much by the time the credits roll.
