I didn't think much of the movie. Improbable story, characters not very believable, too long. At some point my BH turned to me and groaned, "This bloody ship is a long time sinking."
And to put in my astronomer's two cents . . . Apparently, the sky is now accurate in the remastered version. In the original, Cameron went for authenticity on the ship down to the patterns on the china. But when Rose is staring up the sky, it's not even a real sky, just a doubled half sky. (You have to be fairly bored to notice that.) With a prod from Neil de Grasse Tyson and the wonders of planetarium software, the new sky looks as it would have on that fateful night.
