What a beautiful film. Behind all the stunning imagery, emotion and story is the relentless discipline to dive every day for 5 years and then discover this bond over a year in freezing cold water. I have been to the kelp forest and gone into the water. To hold ones breath and be still to capture such astonishing beauty over such a long period of time is nothing but remarkable. In an age of staged nature films the simplicity and authenticity of the story is brilliant.
