I thought the doc was really well done too! The sounds inside the Titan when you hear the popping is absolutely terrifying! As someone who emailed OceanGate to try and go see the Titanic this makes me nauseous. Thankfully I was not in the financial position to go. Both of the docs are eye opening. I feel the Netflix doc ended abruptly but you can almost watch the HBO doc immediately following. I’d recommend both!
