James Cameron's Expedition: Bismarck
Scott Hardie: “It was ok.”
Before Ghosts of the Abyss and Aliens of the Deep and whatever underwater documentary with the word "Terminators" in the title that he's going to make next, Jim Cameron went to the ocean floor to film the wreckage of the Bismarck, and this Discovery Channel documentary paid the bill. It's as meticulously researched and patiently narrated as his other films, with recreations that vividly bring the sinking to life, but it's so wrapped up in its WWII lore that it may as well have been funded by the History Channel instead. If you're bored by the minutiae of battleships, I suggest avoiding an entire documentary on the subject, no matter what bells and whistles Cameron adds to the presentation or what depth is added by the submarine angle. Even Cameron seems incredibly bored when he appears on camera.
