Too bad for Steve.
When I first heard that he was stung by a sting ray, I thought that was an odd way to die...considering how many times he has been bitten by poison snakes. But a punctured lung- makes sense.
They may have it all on film. If so, perhaps at some point they will actually show it. He is in no way comparable to Grizzly Man....but similarly, there will certainly be movies about his life and death, and perhaps the looming quesiton of whether they should show the final minutes or not.
