First of all...there is no rose and jack story...although Rose's character may have been taken from the personality of a survivor...the rest is fictional from Hollywood. I thought it was terrrible the way they made Ismay out to be the snooty person...who selfishly jumped into a life boat to save himself. When that wasn't how it happened at all. He wasn't really concerned with the speed of the ship...he was more concerned with the passengers comfort. He made sure the 3rd class women and children got into lifeboats for 2 hours...only when there were no more women and children in sight...he was ordered to get into a life boat along with another man...named Carter. There both Ismay and Carter took charge in rowing the lifeboat...doing what they could to help. So, the part of Ismay was false. The reality of Mr. Andrews..isn't really known as to what part he played in all this...the movie made him out to be a saint...so thats how we see him. Whether that part is true or not is not known.
Make no mistake that movie stirred quite an interest in Titanic...and people are now looking a little more closly and the wonders of the ship...but the most sought out story of Titanic is the one that is 100 percent true and unglorified. Although we will never know the 100 percent truth we owe it to its members to do our best to tell the story to the best of our knowledge.
I did like the movie...and I do own it...the love story is beautiful...while some may be true we must remember not to believe everything we see.
