“Skybound” (** out of four) was a mediocre action thriller about five passengers (Scarlett Byrne, Gavin Stenhouse, Rick Cosnett, and others) who take off in a plane for a fun-filled vacation but are unable to land after a mysterious disaster occurs on the ground and they are stranded in mid-air. Frightening story isn’t played out for full effect and never fully takes off although it remains watchable. Performances range from passable to one note. Not bad but you can only imagine what filmmakers like Roland Emmerich or Walter Hill might have done with this material.
