Titan A.E was and is a great movie, but the commercial audience is to hung up on genre conventions, and thereby find it clashing. The story is decent, the effects are cool, and the shameless mix of 3D and 2D is a cool mockery of the genre conventions, allthough it was just the result of a too low budget.
And listing "Ladri di biciclette" (The bicycle thief) now that is just pretencious
Yes. Tetsuo is more than a little disturbing. Its a brutal rape of your senses and mind. Thats the point. Try watching it when you are some sense of semi-conciousness.. it might very well change you, and not necessarily in a good way.
Edit: To make this fair (10 is still a stupid number) I'll now list the films that i recommend that I have in my DVD collection, there are more movies, but i cant remember them all. So...
