Before tonight, I had walked out of only two movies in my life. And I have seen a lot of movies in my very long life. This makes three. I tried to stay but just couldn't waste any more of my time. I feel like I grew up and Gilliam didn't. It was sophomoric and boring.
Oh, and the comments that you might not like it if you don't know the novel -- not so. I have studied the book in Spanish, seen the musical, and know the story like the back of my hand.
