Well, I'm not going to, 'cause I didn't hate it. ^_^
But I don't let my opinion of a film be dictated by whether it's most watched. I remember when it was extremely famous, kid. I was there. ^_^ I was in fourth grade when it came out. It was one of my classmate's favorite films ever. (Don't know if it still is; we didn't keep in touch.) Everyone, including me, was talking about it (though being young, pre-adolescent boys, my friend and I weren't talking about the beautiful, tearjacking music, the heartfelt yet tragic romance that is a great parallel for the ship itself, or the excellent, compelling writing; we were talking about the fact that you see a girl's breasts, and that "they" have sex in a car.)
I'm aware that until Avatar (same director, BTW), it was the highest grossing film of all time. (Before Titanic, I think it was Goldfinger, but I could be wrong.)
Nevertheless, it's not really a movie I'll see again. Not just because I can't stand DiCaprio (I'll hate on his performance in that and Gangs of New York all I want), but just because it's not my genre. Sure it's great at being a love story, but I'm not a huge fan of love stories in general. I do like love story subplots, but not when they're the focus. It's kind of how I feel about Romeo and Juliet.
So, honestly, when it comes to the work of James Cameron, I'll stick with Aliens and Terminator 2. :yes:
