You obviously fail to understand what the sinking of the Titanic meant for History. You like the Lusitania better. Great. Good for you. If you can write a script about the sinking of the Lusitania and convince a Hollywood studio to film it, great. I'll definitely watch it. If you manage to get the interest of the audience in the process, excellent. But until then, you have to accept that people have less interest in ships sunk during a War, than in "unsinkable ships" that sink in her maiden voyage with tons of rich people in them.
