I liked Titanic as well. It's plot may have been a tad overwrought, and it may have been geared towards the adolescent girl crowd, but the sinking was nothing short of amazing. I had a time in junior high when I read everything I could find on the Titanic, and when I sat in the theatre, I was pleased at how accurate James Cameron managed to get things.
Also, don't pass off James Horner's score just because of that godawful Celine Dion song. Not his best composition, but one of his most solid pieces. Just skip past 'My Heart Will Go On,' and you'll be fine.
