I saw the 2D also. I don't toss cookies at 3D, but after the first 5 minutes my brain ceases to notice 3D effects so it's a waste of money to me.
I assume the Pendleton was in ballast? It's hard to sink a tanker with 33 or so separate compartments. Even half a tanker. I thought the waves crossing the bar were way overdone, but...it's Hollywood.
They showed a mythical compartment under the main deck that went right to the point of the break. Actually once you go much forward of the aft superstructure there is only cargo under that deck steel. I also wanted to know who was who in the crew. I assume the Chief Engineer was the main character and the guys who wanted to launch the boats were unlicensed deck. Engineers ARE officers, so there shouldn't have been that much debate over who was in charge. But I can see it developing that way. The forward house would have had the Master, all the Mates, the Radio Officer and the ABs and Ordinary on watch. Off watch ABs would have been aft.
In my experience, a merchant marine crew would have done a lot more swearing and less praying
I don't know when life jackets became orange. It was before my time in the mid 60s.
