Query: Sleep-Inducing

I have three things to say about this film:1. The pace was so incredibly slow that the film was rendered unenjoyable. I get that it was intended to be serious, but it was serious to the point of stagnation. It was serious like a graduate school lecture is serious, but not particularly enjoyable.2. The lighting was too dark. Again, I get that it is supposed to be a film with a dark, grave subject matter, but I would also imagine that the audience is supposed to be able to actually see the film. I found myself squinting and wishing that someone would turn on the lights.3. The characters left me cold. I was unable to care about any of them, even Angelina Jolie, and I usually like Angelina Jolie. I just found myself wishing that the film would end. It had a high "so what" factor. This was compounded by the long length and overly complicated plot.I really liked Robert De Niro's previous directorial effort, "A Bronx Tale." Delightful film. What happened?
