Donnie Darko is a sad movie.

Sad Mecha=amused Lecter.

Please, emo some more for us, Mecha.

A scanner darkly is sad, and a major mindfuck.

but mostly a mindfuck.

I find Primer to be sad and it has more 'fuckery' than A Scanner Darkly.

[EDIT] From Donnie Darko, to A Scanner Darkly, to Primer. Are there 'geekier' movies to add?

[EDIT2] Brazil.

Gattaca!

And now for something completely different: http://www.imdb.com/title/tt0080752/
