'Fraid I didn't like Titanic. Couldn't get over DiCaprio, and in any case, I'm not a fan of the genre.
For the longest time, I considered Amadeus the greatest film, but lately I've been giving a LOT of props to Quest For Fire, for having a narrative wherein the story is simple enough to follow, yet there's not a single line of recognizable dialogue. Nevertheless, I knew exactly what was going on, I knew the four main characters very well, and its a very inspiring story to boot, an hour-and-a-half illustration of the bit from the Dao De Jing:
"Give a man a fish, and you teach him for a day. Teach a man to fish, and you feed him for a lifetime."
