Hard to add more, it is a really great disappointment, using black and whites to be considered "art"... indeed the photography is good, but deserving no more than a short film not such a long, tiresome feature time, maybe that should be Cuaron's next step, and leave the feature films alone, he's definitely found his limit with Gravity, and when running out of ideas or serious projects, he just wanted to pay tribute to the place he grew up in, definitely nothing more than a whim with a lot of marketing behind it.
