(CNN) There's a great special to be made about "Titanic," the movie; and Titanic, the giant ocean liner that sunk 105 years ago. "Titanic :20 Years Later With James Cameron" splashes down somewhere between the two, and in the process almost completely misses the boat. And Cameron's passion for and knowledge of the subject obviously shines through. The special also seeks to incorporate a more human element, with Cameron interviewing descendants of passengers who either survived or perished aboard the ship, including relatives of John Jacob Astor, Molly Brown, and Isidor and Ida Straus. It's a promising idea, but mostly plays like an excuse to have these family members pat the director on the back for how moving they found the film to be.
