“The Summoned” (*1/2 out of four) was a drably done supernatural horror thriller about two couples (J Quinton Johnson and Emma Fitzpatrick / Angela Gulner and Salvador Chacon) who go to a self-help retreat but they soon find out that this retreat (yawn) has a sinister side beneath its otherwordly veneer. Relatively well-made but covers all-too-familiar territory without any shock value or scares. Cast of decent actors helps but this overall feels like reheated Jordan Peele.
