I have not even finished it.

I'm right there with you. I also very rarely give up on a film, and when I do it is usually about 15-20 minutes in, and it's obvious to me that I am going to hate the film.

However, where this tedious affair is concerned, I actually turned it off with about 20 minutes left. Of course, I had stopped giving it my full attention long before, not that it required one's full attention, of course.
