“Arrival” (*1/2 out of four) was a boring sci/fi snooze about a linguist (Amy Adams) recruited by the military to interpret alien communications. You keep thinking something significant is going to happen but nothing ever does, as film plods on for nearly two hours. Adams is terrific as usual but is unable to enrich this weak material. A real disappointment from director Denis Villaneuve who directed the superior “Prisoners” and will be directing the upcoming “Blade Runner” sequel. And what a real waste of a fine supporting cast, including Forest Whitaker and Jeremy Renner.
