The movie touches on plenty things. It paints a good picture of the society of 1900, and the clash between nouveau riche and the old rich. For example, the fat lady is laughed at and not respected by the other women, because she doesn't have a good last name, just a husband that struck gold in the west. Then, the director touches on how money ruled everything, and was more significant than safety. One of the important, rich guys basically forced the ship captain to go at full speed even though it was not a good idea, and he ignored the iceberg warnings because they wanted to get to America a day early, because of publicity. Deadly mistake, I might add. The movie portrayed a really good sense of survival of the fittest and how people's true colors come out when their life is at stake. For example, one of the crewmen didn't want want to open the gate for Jack and Rose towards the end of the movie, because he was just fending for himself. Then, there's also Cal, who found a little girl crying by the side and swooped her up and posed her as his daughter, just to get on the safety boat. But, what I personally liked was how Mr. Andrews, the owner of the boat, one of the key captains, and the musicians acted in the end. The musicians kept playing music even though nobody was listening, and even though they knew the end was coming. They were going to die, doing the thing they love the most. Mr. Andrews didn't want to save himself because he was the key guy in the making of the ship and decided that if the ship is going to go down, so is he. The key captain, towards the end of the movie as well, retreated to the main cabin, where he commandeered the ship, and basically committed suicide. Then, some two rich men refused to wear the life jackets and dressed up in their best clothes, and just sat in the lobby. That's how they wanted to go out.
I mean, there's so many great things in the movie aside from the whole Jack and Rose fiasco. It's too bad you guys can't see it. Also, love is one of the best and frequently used universal themes in movies, yet you guys knock it for being a love story? Come on, get past your machoism. Not to mention that Titanic is the most popular motion picture of all time.
The movie is fictional and its purpose was never to portray the truth about what happened with Titanic, so you can't knock it for that.
