I could honestly not listen to some parts of the awe inspiring footage for the shouting and wailing music. This type of music is so divisive I don't know why they didn't just use emotive classical music. It spoiled the whole documentary for me. What I did see with the sound turned down was amazing. The couple seem to have a death wish at times and are more thrill seekers than volcanologist. The footage they filmed is incredible though. To see the devastation volcanos wreck on human and animal life is heartbreaking. This is how our amazing planet began and to honour the death from our past we should do more to save our future.
