"By the time we're done testing it, I believe it's pretty much invulnerable" "And that's pretty much what they said about the Titanic"

It's good for describing everything that lead to the final dive, but there's almost nothing about that fateful dive if not the last 3-4 minutes of the documentary. I was expecting at least 10-20% of the film about the last dive, but I was wrong. All in all, I still recommend it. It's a good insight into an issue that happens in many big companies and corporations: visionary, delusional, and arrogant CEOs that eventually destroy their company with their own hands by silencing inside critics and constructive feedbacks. Unfortunately, this time it lead to the deaths of five human beings. You can't be arrogant with science, and this is evidence of the consequences of doing just so.

Anyone saying it doesn't explain what happened on the final dive has a comprehension issue.

Like sonar: by sounding off each aspect of the depths, a clear picture of what lie down there emerges. This well-researched documentary surprised me because I didn't think there'd be enough to say about the 2023 Titan sub implosion to fill an hour and forty minutes. Yet by interviewing literally everybody who could provide insight into each angle of the disaster, we get a complete picture of what happened to the submersible and its ill-fated occupants.

There was an inevitability to the failure of the Titan submersible. That is the story told in this documentary in a considered and thoughtful way; how the gradual loss of expertise from the project eroded its already thin safety margins to breaking point. That was combined with the single-minded, one might say blinkered, approach of OceanGate's CEO, Stockton Rush. He clearly wanted to be remembered by history; well, he's going to be, but not in the way he likely thought he would be.
