This is one of the most gripping, emotional, and dynamic documentaries I’ve ever watched. The way this documentary was put together made it a non-stop watch, must see till the end. The way these men worked together to try and save one of their own was remarkable! The one question I ask at the end of watching this remarkable story, is: “Is there some additional added protocols that can possibly be added to ensure added measures to ensure more safety for ALL involved in such a treacherous environment?” Final word, I’m so glad Chris was able to continue on with life and kudos to him for going back to what he loves doing...diving! This documentary is a must see!
