I personally didn't like it. It didn't flow for me. I didn't like it because this documentary could have been told in half the time.
Now onto John Chau's death, I do not feel bad at all. He was given several warnings by the tribe every time he arrived on their shores. He was well aware of it being illegal to be there, yet he paid people to take him out there.
He should have taken their first warning and never returned. Had he done that, he would still be alive. He could done the same with people who would have welcomed him. Now his family has suffer for the rest of their lives.
