After reading the other comments, I was glad there is such a common consent and unanimity on the fact that the part about the ship was good while the plot, particularly the love story, was naive and boring. Even the dialogue is interesting and relatively witty in the parts about the ship and the characters other than Jack and Rose, while all conversation between the two lovers is boring and naive. I am surprised there wasn't much effort in creating a more mature and deeper love story, especially with the effort put in the movie as a whole. James Cameron did a very good job directing the ship and her sinking, characters like Moly Brown were amusing but there was nothing special about the main characters. I wonder what was behind the choice of Leonardo DiCaprio for that role, given his young look (One expected a more mature looking man). I would advise people to watch it and appreciate the technical effects but with low expectations of the plot.
