Now THAT'S what I would call a authoritive answer!
I finally got to see GotA and was absolutely blown away! As if some precurser, an omen if you like, early that morning, on a cable station, I watched a large part of "Creature from the Black Lagoon". I say this because, as many of you know, this was one of the early 3D flicks (And I remember when it came out!). The problem in those days, of course, is that Richard Carlson would be right in front of you and the wall behind him would be in the next state!
GotA, even for those NOT interested in the Titanic, is a treat for the eyes - you literally catch yourself ducking poles or trying to look over the ship's railing. I DID feel as it I could just reach over and touch the capstain or feel the stained glass. What a triumph for Cameron et al.
And, IMHO, the ghosts, walking the decks, reliving the crisis, were VERY effective. Although I DO wish we could've seen more of Titanic, I really wasn't put off by Bill Paxton (a good old Texas boy) or any of the other actors. Tickled to see Marschall as Ismay and Lynch as Andrews, tho'.
Best regards, all
