I would like to just put in a plug for the Madonna classic Body of Evidence for worst movie ever. In fact, I saw it in a theater with a friend after agreeing that if it was NOT the worst movie we had ever seen, we would walk out.
We stayed until the end. Poor Willem Defoe.
At this point, I think I will go with Sergio Leone, Once Upon a Time in the West because (among other reasons) movies just don't take time to linger over things anymore the way that his movies do. The opening scene is amazing.
The dialogue, what little there is, is also amazing. "YOu can't trust a man who wears a belt AND suspenders. The man can't even trust his own pants."
And the music is beyond amazing. Words cannot describe how great the music is.
What is at the top of your movie to-rent list?
