Crouching Tiger, Hidden Dragon. I mean, just what was the point of her jumping off into the abyss there at the end? If anyone can enlighten me, please do.
A close second is Chan is Missing. Another inexplicable Chinese ending.
Other than the endings they are great movies though.
I don’t agree about 2001: A Space Odyseey. In fairness to the people who posted though, I bet you weren’t even born when that flick came out. Even then it wasn’t the most obvious and easiest to understand movie, but if you were into the social enlightenment movement, so to speak, it made sense. Personally, I think that the book is even more confusing, but I never liked Arthur C. Clarke as an author. Too roundabout and sillyfosical in his prose. Coincidentally, I just recorded that movie this last week and I am going to watch it soon, not having seen it for at least a couple of decades.
