Thanks for the comment, Sionna Raven! But, actually, about Titanic: a cousin of mine, working in the Merchant Marine at the time, did actually say that he thought the crew of the Titanic could have behaved the way they did in the film. He loved the movie, and couldn't see why I found it offensive. And my dad, a music teacher who was offended by "Amadeus", had his 13 and 14-year old students telling him the movie was the exact truth. Too many people do take movies as history; too many do think what they see is, and must be, true.

Anyway, I do find Titanic offensive. It's true, though, that Harry Potter is more offensive, since Rowling claims she intended to say something serious about racism and genocide.
