I think if you want to TRY to understand a place, and having been here many years I still do not, you have to read many different things from many different perspectives, good and bad.
The idea that a person who writes negatively about Buenos Aires or Argentina is unhappy is judgmental and closed minded in and of itself. I have traveled many places around the world and loved all of them, opening myself to the unique beauty and wonder of each place, each culture, each people encountered on my travels. I dislike Argentina and Buenos Aires and I am a very happy and fulfilled person, even though I live somewhere I'd rather not be. It's interesting, it's educational, it's endlessly amusing and because of these things, the way people here think and live, I am reminded daily how fortunate I am and how wonderful my life truly is.
I would, if I were trying to learn about Argentina, read all the above, and a lot of Borges, and watch the movies, and Open Veins of South America, and all with a grain of salt and an open mind. Then I would talk and talk and talk to people, also with a grain of salt, and just take it in to ponder for years. You'll still never really get a complete picture, but hey, you'll know more than you did...
