“Barbarians” (*1/2 out of four) was a bloody bore about four friends (Catalina Sandino Moreno, Iwan Rheon, Tom Cullen, Connor Swindells) who come together for a birthday celebration that turns ugly when dark secrets emerge and strange occurrences begin occurring around them. Takes forever to get going but then once it does becomes predictable and over-the-top. Story takes elements of “The Big Chill”, “Suicide Kings”, and “The Strangers” and throws them all into a synthetic blender.
