we ( my wife and i ) really enjoy this documentary movie on the fragile coral reef . a this be in the imax format you really feel like your be dive in the south pacific or the caribbean . we be occasional scuba diver and snorkelers and have always love the magnificent hue of coral reef water . so anyone with similar interest should see this documentary a it make a strong message about the reef and show the beauty we all may lose if leave unprotected . the color be very vibrant and the surround sound be just another benefit add to the great musical score by crosby and still and and nash . you will go home sing all those classic from their deja vu album from the late 60 .
