Drain the Titanic

So much time is devoted to whether the ship broke apart at the surface or further down, and the show teases you it might be answered or given info to suggest a possible break up, but then all you get is some mysterious model about debris fields that never really is explained, video of stoic men looking at computers, some fancy graphics and no answer or data to back up an answer or model of the sinking. Then a blurb about what it might look like in the future and some stuff about preservation. Waste of time.
