Nothing any of you have listed yet even compares to the terrible, slow, grating tedium of "The Lost Highway". I am a big David Lynch fan, and I would normally find some silver lining to anything he did, but this movie is inexcuseable. I dare, dare, DARE you to rent "The Lost Highway" and sit through it, and then I dare you to tell me you liked it, and then I beg you to explain to me why.
If you truly stand behind your choice of worst movie, you will accept my challenge.
