I just think her voice has grown and she doesn't need to scream (as others have pointed out she has in the past) to get her point accross. It seems like a very mellow record, but I don't see that as a bad thing.
I see the point about lacking intensity but I just think it's a different way of her singing rather than her being bored--try to think of it that way instead and maybe it will be a better experience for you?
