Incredibly boring. The crew acts as if they have no training for the mission, always in awe and fear of what awaits them. The endless, overwrought displays of angst are hopelessly unrealistic—but, lest you miss one maudlin moment, each such drippy scene, one after another, drives its point home with awkwardly long closeup shots. It’s hard to get through a single episode without pulling out the phone and seeing what else is on.
