“Leave The World Behind” (** out of four) was a bloated, diffuse melodrama about a married couple (Julia Roberts and Ethan Hawke) who take a weekend getaway to a luxurious rental home which soon takes a turn for the worse when a malicious couple (Mahersha Ali and Myha’la) knocks at their door and turns their whole perspective and viewpoint on reality upside down. Not all that different from “The Strangers” back in 2008 except that movie was leaner and lesser-scaled- and also better. Star-laden cast helps to give this a professional sheen but it’s fatally overlong and overly weird. A strange vehicle for Roberts and even her ardent fans would best leave this one “behind.”
